Removed duplicate horse watchers All applicable disguisetypes are now the same names as entity type. Fixed bug where it sometimes didnt return disguisetype when fed entitytype Added zombie_villager disguisetype even tho its not that big a disguise.. Changed the entitytype I store to the bukkit's version. Should work the same.. Untested ofc. Hopefully broke peoples plugins :)
