Preliminary RBSP support.
Q3 needs retesting. With regard to lightmaps. It currently uses only the first lightmap on the surface, and doesn't yet respond to lightstyles. This can result in some fairly patchy edges, and is a bit darker in those areas. I need to rewrite a few other areas to get the rest to work properly (like how lightmaps are drawn...). Everything else should work fine (this doesn't include working gamecode of course). git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@974 fc73d0e0-1445-4013-8a0c-d673dee63da5
