[0.42.6] Desolation Mod: progress 3

I've cleared the error log. Then I've went and made some tweaking to the mod, then cleared the error log again.

I've decided to reduce the number of tissue material tiers somewhat. The Superior and Alicorn tiers have been merged into the Godlike tier (as there's no alicorns, the tier for super special creatures isn't needed). The Tyrapony tier was removed, and the tyraponies were assigned the common Morphling tier (probably will do so in the pony version, too).

Everything concerning rainbows and clouds has been rearranged. Instead of spectra, you're now extracting raw Arcanite; then you're compressing it into a refined form. It's just one color, too. The chain of reactions to make cloud plastic has been reduced to just one, with a successs rate of 20%. The buildings were renamed appropriately.

I've also added a couple of new creatures (will add them to the pony version, too).
