Playing with moons part 2.

A lot of improvements, but still unfinished:
1) Improved celestial object size (I've measured it with ruler :D).
2) Fading in and out now NEARLY equal to vanillia.
3) Fixed path of moons (they were going in completely other direction than in vanillia).
4) More values from fallbacks.

Now, when I'll realise what exactly is "axis offset", and how to implement daily increment, it will be done.
