added r_shadow_usenormalmap cvar which allows you to disable directional shading on rtlights, looking a bit more like glquake lights, this also renders somewhat faster so it may be of use as a performance tweak for some cards
added an optimized ambient-without-diffuse path in the GLSL shader to help r_shadow_usenormalmap 0 performance
