/hat blacklist support

[Blve151]

What are you trying to do?
There's a bug where taking an anvil fall on the player while wearing a /hat will apply damage to the worn hat. This is exploitable for certain items from mods like Pixelmon.

Describe the solution you'd like
A /hat config blacklist for item IDs that can't be equipped with /hat,.

Describe alternatives you've considered
It may be possible to directly fix the issue of hat items taking damage while worn.
Also if preferred, a cancelable hat equip API event would also be an option to allow other devs to easily workaround this.

Anything else that might help?
No.
