CreateShops MCEdit Filter Update (Updated for 12w25a)

CreateShops Filter: https://www.dropbox.com/s/er747lsxq0u... Invincible Filter: https://www.dropbox.com/s/ijs7hzitmj2... MCEdit for Anvil: https://github.com/mcedit/mcedit/down... I updated the CreateShops filter to handle multi-item trades, and threw in an invincible-mobs filter for good measure.
