Mending Rework

Repairing an item at an anvil costs 0 experience levels, and combining an item with another one that is too expensive stays possible. The mod changes the anvil rules: future combine costs increase, while the default chance for an anvil to take damage is cut from 12% to 6%. Items with mending never take damage from renaming or repairing at an anvil.

Mending gets two changes: a mended item regains 10% more durability than before, and experience pickup lets the enchantment repair items over time as usual. The Unbreaking enchantment is adjusted to work the same way on armor and tools. The mod is server-side only, so players join without installing it.
