Tweak default fog settings for better appearance 
- Increase the default non-volumetric fog density to 0.01 to make
  adjustments more visible.
- Use a less saturated non-volumetric fog color by default
  (a mix of the sky and horizon colors of the new default
  ProceduralSkyMaterial).
- Set Volumetric Fog Gi Inject to 1.0 by default. Injecting GI results
  in more realistic appearance of volumetric fog, at a very low
  performance cost.
