Mantle is derpy and needs fixing

Is this still needed?

Things to fix/add:

• Hood's rotation; atm it follows the players head until the body rotates (since that rotates the whole model, thus moving the hood out of phase

• Whilst capeFrontRight/Left already rotates out of the way when you run, they should also do so when you are holding an item in the respective hand;

• armRight/Left should rotate with the arm. (Do note that there might be some weirdness with the rotations of these two. Poke me if you see weird stuff happen)

• Add a floaty animation (slight back an forth x rotation, increases with LimbSwingAmount)

• Maybe the scale of the mantle can change depending on whether or not you are wearing armour?
