r_precachetextures cvar controls how PRECACHE texture flag is used (0 = never precache, 1 = use PRECACHE flag, 2 = always precache)

rewrite of COM_FileBase
default gl_lightmaprgba to 1 (driver speedup (data bloat, but drivers are often more optimized for it), thought I defaulted it to 1 all along, but apparently not)
model names no longer use COM_FileBase (thus they are the full name, like "progs/blah.mdl" rather than "blah", "maps/start.bsp" instead of "start", etc)
