Tetra

This is an alpha build, it's missing core features and contains game breaking bugs. Don't play this unless you know what you're doing and intend to help out with testing.

Changes:

* hid wood variants that share basic wood stats
* added bamboo as a material

Fixes:
* fixed axes not counting as an appropriate tool for some blocks
* fixed durability multipliers not affecting statbars correctly
* fixed not being able to upgrade enchantment levels using enchanted books
* fixed sweeping edge not affecting sweep damage
* fixed Quark Matrix Enchanting not applying enchants correctly (cred: Noobulus)

Technical changes:
* moved rod-type materials into a separate folder which is now referenced by modules, makes it easier to add new rod-type materials
* exposed several statbar helpers
* fixed enchantment tags being functionally inverted
* added option for addons to add aspect <-> enchantment mappings
