Curse disenchantment function and better XP yield using Lapis Lazuli.

If lapis can be used to enchant weapons and armor, the same should go for removing curses as well and possibly maintaining enchantments for higher lapis costs at the same time.

----- Fewer and/or lower tier enchantments and curses would incur less costs and vice versa.

----- Removing curses would not give experience back, but using lapis in removal of enchantments would yield more experience.

---- Allowing removal of curses would give grinding wheels another purpose on top of simply giving back experience. If this is too strong, then the cost could also be increased to removing one tier, or an entire enchantment, of a cursed weapon.

-----If the weapon has only one tier of one enchantment, the additional cost is not applied in removing the curse.

-----Disenchanting weapons without curses yields experience in greater quantities when using lapis. More enchantments and/or  more lapis would yield more experience to a capped amount.
