Very experimental branch for exploring color and brightness details of the atmosphere. Will likely not lead to any merge.
I wanted to go to the basics of the skylight model, found some differences to the original source. This made me add a huge GUI in the atmospere details panel to find out how much of a difference this makes, only to find out that sky brightness is not at all used from the Preetham model but only from Schaefer. All brightness formulae are included, but not used, a bit confusing...
We could allow switching brightness Preetham/CIE vs. Schaefer, or modifications in the color arguments (the GUI is a nice testbed for that). Of course, the Skybright class should be cleaned up from astronomical position code etc. and extinction could be automatic vs. manually set?
We could also keep the sky color parameter switching for other planets(?)
