Added pumpkin armor. TODO: add LangueRegistry entry, icon textures for
the items, and crafting recipes.
Finished up pumpkin armor, added cactus armor, and added two different
ways of smelting rotten flesh to leather: one directly, and one via
crafting rotten flesh into fleshy hides which can then be smelted into
leather.
