Better Repairs

I didn't like Hytale's repair kit system and I liked the idea of repairing your gear with metals at an anvil instead.

You must upgrade the anvil to repair different tiers of gear.

To repair items you have to add the item, followed by the corresponding metal for it.

Any thoughts and comments are appreciated as to what should be tweaked, etc. I made this for fun and am happy to keep supporting it as stuff gets added to the game (and add mod compatabilities for modded tools)
