Spoike 9ae7e2621d SOFTWARE RENDERING IS BROKEN: DO NOT USE ASM VERSION. 
Lots of changes.
CSQC should be functional, but is still tied to debug builds. It WILL have some bugs still, hopefully I'll be able to clean them up better if people test it a bit.
Precompiled headers are working properly now. Compile times are now much quicker in msvc. This takes most of the files this commit.
Restructured how client commands work. They're buffered outside the network message, some multithreaded code is in. It needs a bit of testing before it's active.
