made a load of functions static (just code style stuff). downloads menu now deselects any autoselected items, to avoid confusion. csqc traces can now hit networked ents. I probably need to make some more tweaks to this. arg completion for flocate+dir+modelviewer commands. fix autosave not cycling saves when using the vanilla save format. fix patch collisions with q3bsp submodels. md3 now supports framegroups too. added some more buttons to make xonotic happy. gl_polyblend 2 shows the screen flashes at the edge of the screen instead of the middle. colormod no longer applies to fullbrights (matching DP). this fixes an issue with xonotic. fix uninitialised local that was causing issues with bones used as tags. rewrote qc search_* to use a dynamic array instead of a linked list. this should make it faster to read when there's many handles open at a time. fte's saved games can now save buffers properly. fix issue with raster freetype fonts (read: coloured emoji). initial support for struct-based classes (instead of entity-based classes). still has issues. execing configs in untrusted packages will no longer run out of sync (fixing a number of afterquake issues). fix stupid bug with the te_gunshot/etc builtins. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5317 fc73d0e0-1445-4013-8a0c-d673dee63da5
