Most of the added code written by RealBadAngel Also adds a couple of additional biome controls to jungle trees and conifers. Also adds a text file describing the biome settings in a human-readable manner. At present, this doesn't actually add anything new, it just refactors the code to allow for more trees, and adds a bunch of biome definitions, tree models, textures, etc. but no code to use them, yet.
