MxO Vista/Windows 7 Fixes (useropts.cfg Tweaks)

[rajkosto]

Why PlayerFX_LightPool_Bright_Scale = 0 and all the GreenShift settings ?
The only thing broken on vista/7 is the model attachment normals arent renormalized, which is avoided by not using smooth shading on models with the first 4 settings
the other problems (such as some specular maps messing up texture binds for every rendered poly, and shadow maps make wrong UV coords for some models making the texture repeat forever on them) cannot be fixed by useropts
