New snapshot 12w32a

Just gonna share the features of the new snapshot- Zombie Villagers, Zombies and Skeletons now wear and hold tools and Armour depending on the difficulty, Villager's will react positively if you trade and negatively if you hurt them, Villagers will not remove trades, but trading something else may be required to renew the old ones, Added the "Command Block" intended for adventure maps. It's not craftable and not in the menu, but its id is 137, The Beacon- Called 'Work In Progress' Basically buffs the player with abilities such as Speed, Haste, Resistance, Jump Boost and Strength. The beacon requires emerald blocks to work so if emerald is used as currency this block will be unavailable.
