Will need to store items server side, so we'll wait until after #10 to do this.

Plan:

• You place the item a bit above the book on the enchanting table.
• Once the above happens, the game shows three enchanted forms of the item you placed in, along with the one enchantment ...? in text below it, and the experience and levels needed below that. You grab/right click the one you want.
• The positioning of the three items rotates based on where you are smoothly, not in 90-degree increments like most immersives do.
• It takes the materials at "grab" time
• The item placed in rotates like an item on the ground does

Stuff will almost certainly change between the plan above and the final result

A lot has changed technically, but overall, it's in what I'd consider a "shippable" state. I'm sure I'll find improvements to make to it, and I'll definitely make sure to gather some feedback, but it is done for now. Closing the issue!
