A new Procedure called "Is Item Enchanted"

Issue description

So I am trying to make a custom enchanting table(After I finish I'll have a tutorial on how to do it) I need to check if the item is enchanted or not so I can't have unlimited amount of enchants on one tool 

Procedure:

Is item/provided itemstack enchanted

 

Also if possible, is there a way that you can say that if the item is a tool?Because I want the enchanting table to work on modded items as well

Issue comments

Also if possible, is there a way that you can say that if the item is a tool?

No, there is no reliable way of determining this.

But I will consider adding the procedure.
