(svn r7565) -Codechange: Rework DEBUG functionality. Look for appropiate debugging levels to
use in debug.h. grfmsg() is now used as a specific debug-function for grf.

(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 r6922) -Feature: Add proper cloning sprites and cursors, different for each vehicle. Big thanks
to MB for the initial design and skidd13 for the iconified version(s).
-Codechange: Change the autorenew sprites from recycle to upgrade (skidd13)
-Codechange: Change the shared orders icon (MeusH)
-Add missing table/files.h file to VS project file.

(svn r6593) -Fix: [depot window] added sprites to the buttons, that lacked one
Also changed the sprites on some of the other buttons to make the buttons consistent

(svn r5346) - Feature: Add 4 new airports. 2 for aircraft, 2 for helicopters.
Commuter airport: Small. 5x4. 3 terminals, 2 helipads.
Intercontinental: massive. 9x11. 8 terminals, 2 helipads, 4 runways.
Helidepot: a small heliport with a depot for helis only.
Helistation: a large heliport with 3 helipads and a depot.

(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 r3096) - Feature: 'HOME' icon to saveload dialogs that jumps to the default save/load directory based on the dialog (added icon to openttd.grf, introduced FIOS_TYPE_DIRECT that allows arbitrary directory jumping).
- Fix: on Win32 capitalize the drive-letter in the saveload dialog windows when it is first opened.

(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 r2868) Change the way NewGRFs are loaded: The loading process i no longer bolted onto the normal graphics loading.
This has two major advantages:
- Removal of a maze of global variables and distinction of cases from the sprite loading routines, which weren't directly related to the loading process in the first place
- NewGRF actions no longer occupy sprite slots - for example when using DBSetXL this saves about 2000 slots! (you could regard this as a bug fix)
If i didn't make a major mistake this change should have no negative effect on NewGRF support, please test!

(svn r2866) Move all functions and tables which aren't directly involved in managing the sprite heap to a new file gfxinit.c.
This doesn't ease the global variable mess, but makes the distinction between sprite heap and gfx loading routines easier.
