(svn r1852) Start cleaning up sprite handling:
- Complement the sprite header struct with a variable sized array for the sprite data and rename it to Sprite.
- Use the correct type Sprite* instead of casting all the time (this causes some "assignment from incompatible pointer type" warnings, nothing serious, will be resolved soon)

(svn r1848) Remove the obscure feature of initialising the edit box with the contents of str_buffr - it was unused anyway.
Remove it from the chat box too, which inherited it via copy&paste.

(svn r1846) - Fix: VS6 project file (bociusz)
- Fix: VS6 fkcing borkdness should be abolished

(svn r1845) - Revert r1835 since it totally screws network compiling
- Fix: fix some VS.NET warnings
- Add missing file to VS.NET project file

(svn r1837) GetTileOwner returns Owner, not bool
Also assert() that the TileIndex is valid

(svn r1834) - Fix: NPF does not check the owner of its target, busses try to enter other players' depots. TODO
- Add: asserts to find the v->u.rail.track == 0 problem.
- Add: IsValidDepot(), IsValidTown(), IsValidSign(), IsValidVehicle(), IsValidStation()
- Add: GetTileOwner(), IsTileOwner()
- Codechange: Replaced IsShipDepotTile(), IsTrainDepotTile(), IsRoadDepotTile() by IsTileDepotType().
- Codechange: typedeffed the MAP_OWNERS as Owner. Should be used as variable type.
- Codechange: Replaced a few uint by TileIndex.

(svn r1831) -Fix: Scenario Editor now handles human-made roads better (try to build
a city layout before placing the city, finally that works very nice)

(svn r1826) -Feature: a brand new OldLoader so OpenTTD is TTD(Patch) compatible
again.. kind of anyway. Still needs work for the extra chunks
TTDPatch provides, and which we use too, but not in the same way..
- Also, no longer BE is a problem, reading is BE/LE safe.
- Tnx to Bjarni for the BE testing, Tron for the help on the BE,
Darkvater for helping out, and Mek for providing me with the correct
information regarding TTDPatch savegames

(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 r1817) -Codechange: Moved depot-functions to depot.c
-Codechange: Added wrappers around depot-access (GetDepot no exists)
-Codechange: Made depot-functions a bit more logic (no longer
GetDepotByTile crashes your game when you request it on a non-depot tile)
-Add: made depots dynamic (yes, 64k depots are possible now)

(svn r1799) -Codechange: [ Multistop ] Added debug class "ms" and more debugging
output for multistops

(svn r1797) Clean up TileLoopClearHelper() a bit:
- if cascades -> switch
- uint -> TileIndex
- (uint)-1 -> INVALID_TILE
- don't treat non-flags as flags

(svn r1792) Revert r1761 and set fallback values via ?= for CC and CXX as there seem to be platforms (MorphOS) out there which don't provide some proper defaults.
Use gcc and g++ as defaults, because cc and c++ aren't available either. *sigh*

(svn r1790) Make CmdPlantTree() and related functions more safe and (hopefully) more readable:
- check if end tile is on the map
- uint -> TileIndex
- if cascades -> switch

(svn r1786) -Fix: unitnumber is increased to 16bit, so now you can have up to 5000
trains in one game (instead of the 240 which was the current value).
Default max allowed vehicles per type is changed:
Trains: 500 (old 80)
Road: 500 (old 80)
Ships: 200 (old 40)
Aicraft: 300 (old 50)
(Tnx to Celestar and Darkvater for checking the patch)

(svn r1785) -Fix: space-correctness in road_cmd.c, and one wrong line from last
commit (tnx to DarkVater)

(svn r1784) -Fix: removed ClosestTownFromTile where possible, or replaced it
with _map2-data if possible (Celestar / TrueLight)

(svn r1775) -Fix: The NPF patch setting was not synced in network.
REMINDER FOR ALL DEVELOPERS:
We do have 2 patch-setting-arrays: player-based, server-based. PLEASE
put your new patch setting in the right one... thank you :)

(svn r1773) -Fix: [ 1114950 ] Game crashed sometimes when there were no industries
in the map

(svn r1771) -Add: Industries are now dynamic (up to 64k industries). Generating
1kx1k maps should now be much faster, and give more than just oil-stuff ;)

(svn r1770) -Fix: Hopefully last pieces of code that are containing a station-id
(and should be an uint16, not uint8)

(svn r1768) -Codechange: Store town index in _map2 of town tiles
Moved house type from _map2 to _map3_hi for MP_HOUSE
Moved foundation and roadworks from _map2 to _map3 for
MP_STREET
This increases game speed by a factor of around 15(!) if many cities are around.
Converting an old game is done automagically, but can take a while

(svn r1766) - Feature: Aircrafts will now go to the nearest hangar if the next airport in the orders do not have one (helipads)

- Fix: sometimes aircrafts would not go to the hangar even when they should. They do now

(svn r1764) -Add: dynamic towns, you can now have up to 64k towns (let me know when
you have that amount of towns in a map ;))

(svn r1762) -Codechange: renamed 'MemoryPool' to 'SettingsMemoryPool' (we need
MemoryPool for general-dynamic-arrays)

(svn r1761) Don't set CC and CXX
If somebody tried to use alternate compilers via an environment variable the assignment in the Makefile simply overwrote that.
