Some memory leaks fixed. latency with the nq protocol over loopback is much reduced. Terrain: now mostly a property of a (q1 for now) bsp map, file format changed, glsl now built in, terrain editor builtin improved/changed, holes supported. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4067 fc73d0e0-1445-4013-8a0c-d673dee63da5
