Metology

I have been working for over a month on this so I hope it is good enough. :)

This contains the following NEW features:
* Armor, and armor slots
* Enchant and smoking crafts (just a crazy idea I whipped up)
* Lua entity particle convenience (its in Lua, not C++)
* Animation blending (I'm not sure I got this right...)
* Achievements
* Lua entities can choose whether to staticize
* Lua HUD control
* Camera anim (you know, hand goes down when changing items. make it look better)
* Blocking

Sorry for the mass of commits...
