Allow Over-Enchanting

This mod allows you to combine the enchantments of items in an anvil over it's vanilla limit (technically up to the integer limit). The only limit is the "Too Expensive!" message, which you can disable using any of the many, many mods that remove it.

This works best with mods that give you items with impossible enchants, or if you want to create ridiculously stacked enchantments for items. (Want Infinity II? Now you can!)
