WIP Request: Planet generation is harshly hardcoded, can we get some options on them?

Right now, we only have one color and one shadow mask for gas giants, and it is a bit of an ugly brown color.

Would it be possible for Chucklefish to add randomization to color and cloud mask picking through celestials.config, so we can have a) prettier and b) randomized gas giants around, like planets with the dynamics/<num>.png selectors?

Check how beautiful gas giants can look:





These are sadly hardcoded right now to only read one file.

Another thing would be adding a hue shift to shadows/<num>.png's depending on the system's star, which is not possible right now.
