Separate Melee and Ranged Thorns

Currently Thorns effects both ranged and melee attacks. By the name, you'd assume it would only affect melee hits, but it also affects ranged attacks too. It would add more variety to combat if Thorns would only effect melee attacks, and a new enchant would be Thorns for range. Personally, I think Karma would be a good possible name for it. And the only way to bypass both Thorns and Karma, is to use damaging potions instead.
