(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)pull/155/head
