Updated All Items.

All items will no longer show the black 'ID: "id"' text on the item.
This makes the text look a lot nicer.

Also fixed a couple items that had display issues, like the patchwork
armor.

Also added Ender_Essence and Ender_Temper.
Updated Enderman Loot Table

Endermen now drop Ender Essences and Ender Tempers, as well as rarely
Enderdragon Ore (for Thunderfury)
