(svn r7449) -Codechange: Rename _path to _paths as it is technically more correct, but mainly because
it interferes with OS/2 symbol in libc (psmedley)

(svn r7274) -Codechange [utf8]: Add input/output unicode support. This actually only changes win32
since it uses UTF16 for file access. To keep os-specific code to a minimum, OpenTTD
uses UTF8 internally everywhere, converting to OS-type when needed (save/load/screenshot/etc.)

(svn r6930) -Codechange: Move industry name into IndustrySpec
-Codechange: member color_map is more related to random color, rename it as such

(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))
Courtesy of Tron.

(svn r6454) -Fix(r6108) : Allow custom currency to display both prefix and suffix
-Codechange : Divide rate of conversion from grf by 1000, to match OTTD internal system

(svn r6169) -Codechange: Use GetString() instead of GetStringWithArgs() which should be
integral to strings.c

(svn r6108) -NewGRF Feature: Implement currencies replacment via grf file.
All properties can now be modified i.e:
Introduction date for euro conversion
Currency name, decimal separator, currency symbol (before or after amount)
and the rate compared to the base currency, the british pound

(svn r6047) -Codechange: FOR_ALL now _only_ loops valid items, and skips invalid ones
-Codechange: use IsValidXXX where ever possible
Note: both changes to prepare for new pool system, which needs those changes.
For every pool there are 2 ugly lines, which will be removed when done
implementing new pool system.
Based on FS#13 by blathijs, partly implemented.

(svn r5926) -Codechange: make _cur_year contain the full year, instead of the offset since 1920
-Codechange: store all year related variables that are _not_ stored in a savegame/transported over the network in the same format as _cur_year

(svn r5918) -Cleanup: rename ConvertDayToYMD/ConvertYMDToDay as they really convert a Date to/from a YearMonthDay.
-Cleanup: swap ConvertDateToYMD's parameters to make the order consistent with the name of the function.

(svn r5916) -Cleanup: use MIN_YEAR/MAX_YEAR for the year boundaries and BASE_YEAR when comparing _cur_year with a 'full' year.
-Cleanup: replace some magic '1920' values with BASE_YEAR.

(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 r5464) [Behaviour Fix] : When starting the game, the system will now verify the presence of music files in gm forlder.
A song can now be removed from the programmed list (in custom list 1 and 2) by clicking on it.
Added music.c[ch] files, to make it all a bit cleaner.
Now, the name of the gm file is associated with the title of the song.

(svn r4854) - Codechange: don't assume a short format month is 3 characters -- copy the string in the same way the other parts
are copied.

(svn r4493) Newgrf : Action 04. Beginning of implementation.
Some TODOs left, but the core is there.
Thanks to Peter1138 for code, advice and patience
And to Patchman for letting us define a lot of langids :)

(svn r4126) - Feature: A new multi-lingual multi-measuring-unit system:
- Replace miles/kilometres game option with a general measuring units option.
- Add {POWER}, {WEIGHT}, {WEIGHT_S} and {VOLUME_S} (_S for short) tags to the language/string system.
- Add SI as option for measuring units.
Language file updates to use the system will come soon.

(svn r4105) - Feature: Add proper ISO-8859-15 <> LOCALCODE conversion. As the mess that is makefile can't properly support it at the moment, it is only available for MACOSX. Windows doesn't need FS conversion and I have no idea about OS/2 so it's disabled for them.
- CodeChange: Change the function GetCurrentLocale(). It returns the locale from some default environment-variables, plus a custom one defined as parameter. If all fail, it tries $LANG.

(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 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 r2879) Major step twoards ISO-8859-15
Add several missing chars:
- Š/š (S with hacek, all sizes)
- Ž/ž (Z with hacek, all sizes)
- Œ/œ (OE ligature, all sizes)
- Ð/ð (eth, large font was missing)
- Þ/þ (thorn, large font was missing)
- º (male ordinal sign, all sizes)
Also move Ÿ (Y with umlaut, all sizes) to the correct position in the charset
To add some chars it was necessary to shuffle some OTTD specific chars (arrows, transport type markers) around

(svn r2597) Feature: [string system] Support cases.
- Cases are used to change a string, such as Coal Mine, depending on the surrounding context.
- Cases are defined like "STR_4802_COAL_MINE.ack :Coala Mina"
- All cases need to be listed on the top of the file like this "##case ack"
- When using the string, type {STRING.ack} to choose the "ack" version of Coal mine.
- Also combined the strgen arrays into a struct, and fixed a bug with SetXY.

(svn r2594) Fix: [strgen] Misc updates to the string system.
- Renamed the plural command to "P" instead of "PLURAL". Now write something like this to append an s on plural: {P "" s}. (You can optionally still add an argument index to explicitly specifiy which number that's used)
- Removed the pluralized cargo strings from the string files. The new method is to use the plural specifier {P}
- Added support for genders. First add "##gender der das die" on top, then use {G=der} on a cargoname/industry to set the gender, and to switch between genders do something like {G neu neu neue} {STRING}
- Updated the swedish/english translation with P strings.

(svn r2592) Feature: [strgen] New way to specify plural forms.
- {NUM} {PLURAL 0 car cars}: Prints either car or cars depending on if the argument 0 is plural.
Also supports languages with weird plural forms such as Polish.
The plural format needs to be specified in the beginning of the langfile, like "##plural 7" for Polish.

(svn r2580) Change: Added {INDUSTRY} command for printing industry names instead of the old {TOWN} {STRING} way.
- The formatting of the industry name can be controlled with the string STR_INDUSTRY_FORMAT.
Change: Changed several occurences of {STRING1} into {TOWN} to get rid of townnametype being used directly.

(svn r2572) - Codechange: [string] Changed string system so it's not as dependent on decode_parameters
- Feature: [strgen] Allow changing the order of parameters in translated strings.
- Use {1:TOWN} syntax to set the order.
- Codechange: [strgen] Rewrote lots of strgen internals.

(svn r2564) Fix: Fixed conceptual issue in network_gui.c. AllocateName is not meant to be used by GUI-code, because it modifies the "game-state".
Added a way to bind a C-string to an openttd string which doesn't modify the game state.

(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 r1825) Further style improvements:
- uint16 -> StringID where appropriate
- if cascades -> switch
- remove redundant ifs
- misc. stuff

(svn r1820) Style cleanup:
- indentation
- 0 -> '\0' in string handling
- whitespaces
- space after for, switch, etc.
- don't treat non-boolean values as boolean
- space before and after binary operators
- bracing style

(svn r1603) -Fix: unused variable in FormatTinyDate
-Fix: added void to all win32.c functions as well

(svn r1598) Feature: Message history now is stickyable and resizeable
The news messages are now precisely cropped according to pixel width to fit optimal into the window.
Introduced a new date format: DATE_TINY, which is ISOish.

(svn r1407) -Codechange: changed a lot around _stations, _vehicles, _towns and _industries
(in prepare of dynamic arrays):
- DEREF_XXX is changed into GetXXX
- All direct call are directed via GetXXX
- struct Industry has now an index-field
- ENUM'd some stuff
- Replaced home built loops with FOR_ALL_XXX
- Added _stations_size, _vehicles_size, ... which gives the length of the
array (which will be dynamic in the near future)
- Changed lengtof(XXX) to _XXX_size (e.g. _stations_size)
- Removed all endof(XXX) (because mostly it was part of a FOR_ALL_XXX)
- Made the sort-functions of all 4 dynamic
- Made all 4 Initialize functions more of the same
- Some minor tab-fixing and stuff
(tnx to Tron for proof-reading my 100kb patch ;))

Note for all: please do NOT directly call _stations, _vehicles, _towns and
_industries, but use the right wrapper to access them. Thank you.
Ps: please also do not use 'v++', where v is of type Vehicle *.
