enchantment transfer (by jmurph669)

so, many people can find some crazy enchantments, like mending, or silk touch. but with one small problem. it would be on like a hoe, or a shovel. so, my idea is that you could have a new option on the grindstone , like a different tab on the U.I  labeled enchantment remover. unlike removing an enchantment normally, giving some exp, this option could turn the enchantment back into a book, costing around maybe 5 levels, and that number would gradually increase the better the enchantment. thats my idea, please see this mojang.
