Nano Saber beheading

As the title implies: a modification of the Nano Saber's properties to give it an innate Beheading enchant (of some level). Ideally, only applicable when charged.

This one just makes thematic sense to me - a precision cutting blade should be able to cleanly remove something's head from its shoulders, no problem. (I'm just unaware of how much code it would take to pull that off.)

It's not, as far as I can tell. I've just gotten so used to playing modpacks including it that I'd forgotten it wasn't part of the base game.

I assume there's some sort of multiplier for specific loot that it tweaks somewhere, but I've never dug into the code myself.
