Ender Eye Sword — 1.3.1

Small but meaningful update.

---

[+] Unbreaking now interacts with the sword's ability — higher levels reduce durability cost on right-click (20% / 40% / 60% chance to spend only half)

[+] New advancement: Definitely Not Breaking — obtained by having the sword with any level of Unbreaking

[±] Strong Detachment is no longer incompatible with Mending

[-] Removed leftover debug mixin
