In-Game NBTEdit

This is a Minecraft mod, originally from November 2012. Based on copygirl's external tool NBTEdit, In-Game NBTEdit allows users to edit NBT tags of entities and tiles while in-game.

The code is fairly messy - I would recommend porting this to GuiLib, but that is easier said than done.
