'hrendz' and 'vrendz' variant functions now C
 - inline assembly varients removed
 - C varients uncommented
 - opti4asm no longer needed, all instances of it (voxlap5 and v5) removed
 - opticast now no longer has any clearMMX calls

Induced Bugs (in game.exe):
 - Rendering is noticably lower framerate, especially animaions (or maybe they are just more noticable)
 - player is much faster
now MSVC warns about persistant mmx registers so such hacks can be fixed
