GitLab

Add the new DeepRealms, inspired by Zeno's fork, and add the new salt
crystal, obsidian, and coal dust biomes.

Slight conflict of ideas with another mod.

Lots of values moved to config.lua, split nodes and functions into their
own files.

Added craft recipes for Mycena Essence, Glow Mese Crystals, and a
reverse recipe for them. Fixed selection box for mycena mushrooms,
adjusted crystal variation rates.
