ButterBee 1.1.2

Slight changes to the Lava Chicken disc obtainability. Should be compatible with previous ButterBee versions.

• Removed all Zombie loot table changes
• Zombies riding Chickens now drop the Lava Chicken in the Nether only when killed by a player
• The Nether Chicken is no longer guaranteed to drop Lava Chicken if it was a jockey, instead all Nether Chickens now have the same rare chance to drop the disc
• Chickens can now eat Nether Wart
