New enchantment Kinetic energy protection

 Adds a new type of protection enchantment. I think this enchantment should be exclusive to elytras, and it should be  called Kinetic energy protection I/II/III/IV. It would reduce the damage done by kinetic energy when flying with an elytra.

I belive this is something that is missing in the game, especially since the Elytra doesn't have any enchantments that only apply to it.
