Make sure that atmospheric calcs aren't done twice.

The atomospherics were being applied both in the G-buffer and during the sun light pass.  This ensures that is not the case.
Additionally, re-enable specular on the water plane, scale the bloom factor to something more reasonable, and also someone broke specular on emissive surfaces.  That's fixed too now.
