- Deprecating r_shadeMode and r_envMode

Browse Source 
- Added lightingSpecularDiffuse which is like diffuse, but clamps and does a specular calc for the overbrights, and this is also disableable with the new r_shadeSpecular cvar
- Added tcGen environmentWater which is more suitable for water
- Faster bulge code from JK2
- Shutting up TGA loading fatal errors for warnings instead (to hunt down bad TGAs easier)
