added r_part_classic_square, cl_demoreel. fixed a couple of things that the ever vigilant gb spotted. I guess I don't play quake enough. fixed a load of random warnings reported by gcc. many many many warnings remain. I got bored. internal mrt feature implemented, not properly tested yet. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4719 fc73d0e0-1445-4013-8a0c-d673dee63da5
