Ridable Animals (Horses, Pigs) Broken

• Horses are impossible to tame: They don't buck you off and they don't become tamed when you ride them.
• Tamed horses (from previous versions or summoned) can't be controlled, they don't move at all
• Tamed horses don't look at the same direction as their riders
• Pigs cant be controlled either using a carrot on a stick
• Minecarts cannot be controlled with WASD. But powered rails, pushing or simple momentum will allow them to move just fine.
