Additions

 * Shields
 * New tool used for blocking incoming attacks.
 * Holding right click while being attacked reduces damage on the player and the durability of the shield.

 * Can be combined with banners of the same base color to transfer its pattern.
 * This does not consume the banner.
 * You cannot attack while blocking.
 * Crafting recipe: One column of wool (of the same color), one column of planks (any kind), an iron ingot in the middle of the last column.
 * Can only be repaired on the anvil.
 * Requires wood.
 * Cannot be enchanted on the enchanting table, but can have Unbreaking added via an enchanted book.
