Sunsky / Atmoshphere:

- Added blending mode and factor option, so it's more clear and
  controllable what happens with it. Also nice for crazy effects
  of course!
- Preview render now shows preview for it too

On the todos:

- have this in World buttons (as well) for quicker sky setups
- review math of color clamping and scaling, this is definitely 
  not good... but a fix will make old files look very different.
