Planetary Light improvements

[Weezer]

I really like the Planetary Light for space scenes (in C4D), but it currently seems only able to make misty blue planets. It would be great if we could alter the density of the atmosphere – so the Ground Albedo map is clearer, the atmosphere 'depth' – so we could see more of the atmosphere itself at the planet's edge – and the ability to change the atmospheric colour for more sci-fi-style planets.
