*	[FIX] No more asserts in sigmod	Ben Boeckel	2008-11-08	1	-0/+56
	[FIX] Moved to using *ById instead of *Index methods in sigmod [FIX] Tilemaps are now collaged (not completely done on the editing side yet) [FIX] Removed the resource files (drawn natively instead) [FIX] ATBTimer now uses the built-in QTimer in a QObject [FIX] Coordinates are now edited on the map for warps, trainers, and effects [FIX] Tiles are now completely scripted [FIX] Config is now thread-safe git-svn-id: https://pokegen.svn.sourceforge.net/svnroot/pokegen/trunk@308 6ecfd1a5-f3ed-3746-8530-beee90d26b22
