Anvil Tweaks

The Anvil

• Remove the experience cost and do not increase the repair cost component when repairing gear with raw materials.
• Only increase the repair cost component and charge experience when adding enchantments through enchanted books or combining gear.
• When repairing enchanted gear with raw materials, there should either not be an experience cost at all or enchanted repairs could just not increase the repair cost component since it isn't modifying enchantments.

These changes would make repairing items viable while repurposing the experience cost to only affect enchanted gear. The "too expensive" problem would now only appear when attempting to add too many enchantments while repairing items with raw materials would now work indefinitely.
