mods, added aliases for backwards compatibility.
All nodes are named
moretrees:something_sapling,
moretrees:something_trunk
moretrees:something_leaves
moretrees:something_planks
Also, added sideways trunks for all trees and crafting recipes for them, plus
added in the missing trunks -> planks recipes.
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.
