Fixed NPE when itemstack is null

No no longer requires ItemNBTAPI

Changed event listener to priority high so that other anvil plugins can handle events before this one.

Hey guys, quick update for 1.18. Can't grantee this version will work on older game versions.

Changes:

• Fixed anvils not taking levels from the player when the cost is above 39
• Better default messages

no other changes

As of 1.17 sadly, the client now prevents anything above level 39 from being taken out of the result slot in an anvil.

This means you'll need to keep the "Anvil Reset Max Repair Cost" to 39 or lower for this to work.

Title says it all.

This update brings with it bugfixes and improvements as well as one more feature.

Bugfixes:

• 1.16 clients should no longer display the too expensive message even without NBTAPI
• Fixed Reset Max level Cap

Various performance improvements.

Features:

• Added message to tell user that they don't have enough levels and how many levels they would need.

If it doesn't effect you, no need to update.

(Not tested if backwards compat)

You can now set your level cap to anything... below the 32bit int limit
As it will just switch to displaying the cost on your hotbar (As the anvil's client side stuff only says "Too Expensive" with anything >39 when not in creative.

Keep in mind you'll need to regenerate the config if you wish to use this, Not that that's too painful 3 or so lines and all.
