(svn r7632) -Codechange: several small code cleanups of texteff, like moving magic values and defines to an enum and fix coding/documentation style.
-Codechange: make DeleteAnimatedTile a little clearer (pv2b).

(svn r6959) -Codechange: Move GfxFillRect() out of the chat-message drawing loop since we already
know how many lines we are going to draw. On certain architectures this results in a
minor penalty of local function performance if only 1 line is drawn. But starting from
2 and more you'll get a net gain.

(svn r6956) -Feature: Increase the chatbuffer of chat messages. Messages longer than the allocated
graphical box will be wrapped to a new line.

(svn r6955) -Codechange: Change some variable names for _textmessage_box, and replace 5 different
global variables with a single struct.

(svn r6884) -Codechange: Add strict bounds checking in string formatting system.
The last parameter should point to the end of the buffer (eg lastof(buf))

(svn r6462) -Codechange: Have GetStringWidth() return width as well as the height bounding
box of the string. Therefore rename the function to GetStringBoundingRect()
and have it return a BoundingRect type of width/height

(svn r5887) -Cleanup: move date related functions, defines and variables to date.[ch]
-Cleanup: fix whitespace related coding style issues in date.[ch]
-Cleanup: make original comments doxygen compatible and remove/change outdated comments

(svn r3181) -Bracing
-Indentation
-Whitespace
-DeMorgan's Law
-Test with NULL or 0 for non-booleans
-'\0' instead of 0 for chars
-Remove redundantly redundant comments (like DoFoo(); // Do foo)
-Join multiple short lines with a single statement
-Split single lines with multiple statements
-Avoid assignments in if

(svn r3078) Some more stuff, which piled up:
- const, whitespace, indentation, bracing, GB/SB, pointless casts
- use the trinary operator where appropriate
- data types (uint[] -> AcceptedCargo, ...)
- if cascade -> switch
- if (ptr) -> if (ptr != NULL)
- DeMorgan's Law
- Fix some comments
- 0 -> '\0', change magic numbers to symbolic constants

(svn r3077) static, const, bracing, indentation, 0 -> '\0'/NULL, typos in comments, excess empty lines, minor other changes
nothing spectacular, just some stuff, which piled up

(svn r2387) - CodeChange: made the saveload code more readable and also removed the 'byte' saveload arrays which means you can save an array of more than 255 elements, or bigger structs than 255 bytes. This doesn't yet solve the problem that a chunk can be a maximum of 16384 big.
- Fix: also fix an unnoticed error in SlSaveLoadConv() due to wrong types.

(svn r2099) -Fix: no longer chat-messages hang when the game wraps around 2090
-Codechange: while trying to find this bug, made texteff.c a bit more readable :)

(svn r1676) Increase the size of TileIndex and TileIndexDiff to 32bits and adapt the save/load data and some other parts of the code to that change

WARNING: If i made any mistake here it WILL lead to corrupted savegames!

(svn r1523) -Fix: somehow mousewheel was disabled on windows using SDL; reenabled again
-Fix: added missing CDECL to ellipsis functions and changed VS6 project file to use _cdecl calling conventions (thx tamlin)

(svn r1312) -Add: Patch which is on by default: population in label of the town
-Fix: Expand town is a bit more agressive
-Fix: Fixed a bug in growing algorithm

(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

(svn r901) Small step in the process to clean up the DPARAM mess:
- reduce to 2 sizes (*DParam64 for 64bit values, *DParam for the rest)
- use inline functions instead of macros
- add assert()s to check for buffer overruns

(svn r624) Merge r377 to trunk:
Remove the memmove special case for MSVC
According to the MSDN it was just plain wrong and memmove was directly used in some places anyway
