(svn r2962) - const correctness for all Get* functions and most Draw* functions that don't change their pointer parameters
- change a lot of byte player types to PlayerID
- beautify header files, same "#endif /* filename */" ending

(svn r2657) -Codechange: The available railtypes per player are now a bitmask, so
that railtypes do not be in ascending order of appearance. Allows easier
implementation or more railtypes

(svn r2602) -Codechange: removed unused variable (disable_computer)
-Fix: Changed some stuff to make server-side AIs possible in the far future

(svn r2595) -Codechange: Introduced "IsSteepTileh" to find whether a tile is steep
(i.e. spans two height levels) and use it throughout the code.
-Codechange: Add CanBuildDepotByTileh to find if a tile is suitable to
build a depot on it. Wraps some bitmagic which seems quite unreadable at
first glance

(svn r2560) Fix: various minor code changes.
Added RandomTile/RandomTileSeed functions to generate a random tile.
Changed landscape routines so they don't assume that the Y map side is a power of two. (support for this is not complete, though)
Changed some frequently used map macros to not compute the values each time.
Silence some warnings on MSVC.

(svn r2391) - Feature: saving games happen in a seperate thread so you no longer will have to wait such a long time (especially handy on bigger maps and multiplayer games). The mouse also changes into the 'ZZZ' state :P. The thread on windows is currently given a little-bit-less-than-normal priority so it should not interfere that much with the gameplay; it will take a bit longer though. Upon the exit of the game any pending saves are waited upon.
- Fix: fixed GetSavegameFormat() so that it takes the best compressor (highest), or a forced one added with the parameter
- Open issues:
1. Don't attempt to load a game while saving is in progress, it will kick you back to the intro-screen with only the vast ocean to look at.
2. The server is disabled from threaded-saving, but might be enabled in the future.
3. Current implementation only allows 1 additional running thread.
4. Stupid global variables.....grrr
Big thanks for TrueLight and the amazing memorypool :D

(svn r2303) - CodeChange (fix): when giving money to other players only allow transferring money that is above your loan. Eg you can't give away your loan.
- Langfix: 'goes down by' 'increases', vv for down in english.txt.

(svn r2297) - CodeChange: server-check the next batch of commands.
- CodeChange: since only the server will be able to modify difficulty settings, leave the checking of correct values besides, and trust users will join legit servers.
- CodeChange: for renaming signs, only check if GetDParam(); eg _decode_parameters is empty ('\0') or not, instead of the extra check of players, etc. That basically does the same thing. Also dirty sign two times when renaming, once before, once after the action. Because if the name becomes shorter and you update only after, garbage remains on the screen.
- CodeChange: made GetMaskOfTownActions() available to the town-cmd to double-check if the action was available to the player. For this purpose the hardcoded _local_player has been removed from the function and is now passed as a parameter.

(svn r2192) - Add greater control to the 'message options' window. Now you can turn off the telegraphc ticker sound for summarized messages, or turn off news-messages altogether (you get a red blot to notify you though). The [<][>] set the settings in one way, while clicking on the option itself, cycles it. This commit also 'fixes' bugs [1166973], [1121484] and patch [1169930].
- I also changed an order of strings from On, Off to Off, On, so this can be used ingame with the WWT_4 widget type.
- Since the newssettings now take 2 bits per setting (off/summary/on) _news_display_opt is widened to 32 bits and the settings code changed slightly to accomodate for a maximum of 16 message-types.

(svn r2161) - Fix: When resizing a window, the button is also visibly depressed
- CodeChange: Use images as arrows in the scenario-date scroller, looks better
- Feature: Clicked buttons with images/text now visibly depress their contents when pressed (eg it really seems like the button is moving)
- Fix: Fix sprite offsets of the arrow sprites in openttd.grf

(svn r2136) - Fix: [ 1174313 ] terrain hotkeys nonfunctional in scenario editor (D,Q,W,E,R,T,Y,U fltr)
- Fix: 'L' no longer opens ingame terraform bar in scenario editor bar, but the land generator one
- Feature: [ 1095110 ] Create Lake and draggable Create Desert tools (initial implementation GoneWacko), also added sticky buttons to land generator and town generator
- CodeChange: moved around some of the draggable tools, demystifying them
- CodeChange: change CmdBuildCanal to allow for XANDY dragging not only X or Y (only scenario editor)
- CodeChange: add some more enums to sprites.
- TODO: merge most of the ingame and scenario editor land terraform code. This can only be done after OnClickButton function is changed so it also includes the backreference to the widget being clicked, postponed to after 0.4.0

(svn r2079) -Add: signlist, shows all signs in the map. Clicking on them, and you go
to the sign. Very needed for coop. You can find it under World Map.

(svn r2075) -Fix: added missing breaks in switches
-Fix: added const for a const variable

(svn r2046) -Codechange: moved all waypoint code to waypoint.c/waypoint.h
-Codechange: rewrote some functions while moving waypoint-stuff
-Add: added support for 64k waypoints
-Fix: made the waypoint struct a bit more logic (no bit-fucking)

(svn r2004) - Fix: [ 1149487 ] Autosave ignoring settings
- Fix: [ 1153926 ] All my settings in vain... IGNORED!
- Change: I hope I got it all right. Pressing 'New Game' (either choosing random or a preset scenario) and 'Create Scenario' will start a new game with the settings and difficulty in the intro menu. Using 'Load Game' and 'Play Scenario' will take the values from the savegame/scenario itself.

(svn r1894) - Codechange: cleaned up the console a bit, wholly unified handling of text with that of editboxes
- Codechange: Introduction of Textbuf struct which not only holds physical data as length but also pixel-constrains (width) and information about the caret
- Codechange: Move Clipboard function to OS specific file. Currently only Windows has clipboard actions
- Feature: Editboxes, console and exit screen also accept the numeric-enter as a yes
- Feature: Navigation through text with cursor keys is possible, as well as arbitrary insertion (also paste) and deletion; both backspace and del keys. Functions DeleteTextBufferChar, InsertTextBufferChar and InsertTextBufferClipboard handle input and deletion. Navigation is done through MoveTextBufferPos.
- Fix: OTTD crash when opening 'add server' editbox
- CodeChange: fix up some stringwidth calculations in gfx.c. You can get the width in pixels of a character by calling GetCharacterWidth().

(svn r1866) -Fix: Intercepted generated maps with 0 towns on it. Currently just an
error() is called, some more graceful handling should be implemented
later.

(svn r1667) - Feature: Signs are now shown in the color of the player who created them
(Note: The player information is currently not stored in savegames. Upon loading a game the signs will all be gray again)

(svn r1653) -Fix: removed CTRL+A and CTRL+B cheats; thanks Hackykid
-Removed executable bits on png files in media dir (svn pd svn:executable <file>)

(svn r1571) Feature: Visually enhanced autorail placing
When using the autorail tool, the rail pieces which are going to be build are highlighted.
If a piece is shown in red, this indicates that the slope/rail combination is impossible. It does not tell you if the rail line construction might not be possible because of other obstacles, e.g. houses or water.

(svn r1545) Add TileHeight() which returns the height (not multiplied by 8)
Replace some direct references to _map_type_and_height with TileHeight()/IsTileType()

(svn r1502) -Fix: [1101889] Crash under windows... stupid typo in player_gui.c ^ should've been &
-Fix: in multiplayer clientlist can only be opened once

(svn r1497) -Fix: [1101179] Crash if generating land while industry window is open. This also happened for towns and the land information window
-Added DeleteWindowByClass() function that deletes all windows of a given class

(svn r1486) -Codechange: moved all 'signs' stuff to signs.c/h and prepared it for
dynamic arrays

(svn r1479) -Added highscore chart (accessible from the difficulty window) with top5 companies for a given difficulty (select the difficulty in the menu)
-Added endgame score on 1 jan 2051 where you are added to the highscore if sufficiently large points have been accumulated. Game is paused while
-These values are saved in hs.dat; added read/write functions for it
-Added code to delete all windows to show charts. There is one issue left: somehow a news-gui pops up in front of the the chart at the end of the game.

(svn r1348) -Feature: resizable windows. Read the comment in window.h to find out
how the system works. All useful windows are already made resizable. Enjoy :)
-Fix: fixed some GUI-glitches and flaws along the way

(svn r1263) -Fix: [Network] Client-names are limited (serverside) to 25 chars
-Fix: You can enter some more chars in the chatbox

(svn r1240) -Fix: OpenTTD once again compiles if ENABLE_NETWORK is disabled.
-Fix: removed some warnings
-Enabled ENABLE_NETWORK on windows again which I accidentally commented out.

(svn r1225) -Feature: SHIFT+DEL now deletes all non-vital windows (only status bar and main bar remain)
-Fix: For everyone who tried to crash the game by opening a huge amount of windows and stickying all of them; bad luck. It's fixed now (thanks Tron for the helpful criticism). First all normal windows are a candidate for replacement, then if none are found, sticky windows. Then..well that should not happen :)

(svn r1214) -Feature: Stickified Industries (list & window), Smallmaps (all three), Stations (list & window) and Towns (list & window). I hope I didn't forget to update a widget somewhere :O
-Feature: With the sticky windows on and some unfortunate resizing of your game it the 'close' button might go outside of the playing field, making it impossible to close. Added an option to the Options menu that closes all windows, even if they are stickified ("Close ALL windows")

(svn r1121) -Feature: Added sticky windows feature. A small pin allows the user to set the window as undeletable and can only be closed by hand. As an example the viewport window has been stickied (thanks to Neko-San)
-To use the feature add WDF_STICKY_BUTTON to the widget description and update all widget-ID's since sticky button will be widget 2.

(svn r1108) -Fix: [Network] Fixed problem around slow clients:
They joined, they got the map, but it took some time before the new
player was created. In this time a player could do stuff, causing a
player-id-mismatch, and the player was kicked out. Now a player get's a
nice GUI which says: registering.. When that is gone, the player is
joined and can play safely. Tnx to Moriarty for bugging me with this bug ;)

(svn r1082) Feature: Chat toolbar
- to chat with all players press Return (or Shift-T) and type in the message
- Press Return again to send the message
