Issue Description:

I'm trying to create a crafting based enchanting system for a modpack, but have run into a slight hiccup. While I can use .onlywithtag to specify specific NBT for recipe inputs I can't seem to figure out how to do something similar for an item with no NBT tags. For example: I create two recipes, one for unbreaking I pick and another for an unbreaking II pick. The recipe for the unbreaking II pick specifies that it can only be crafted with an unbreaking I pick, but I can't figure out how to specify that the unbreaking I pick will only take an unenchanted pick.

What happens:

I can craft an unbreaking I pick with my current recipe, but when I try to craft an unbreaking II pick it assumes I'm trying to craft an unbreaking I pick again and gives me one as the crafting product.

What you expected to happen:

When a regular pick is used as the crafting ingredient a level I enchantment is returned, but when an already enchanted pick is used it returns the next level of enchantment.

Use

item.only(function(item){return !item.hasTag;})

Or if you need it multiple times, do

import crafttweaker.item.IItemCondition;

val noTagCondition as IItemCondition = function(item){return !item.hasTag;};

//For the recipes
item.only(noTagCondition);

Worked perfectly! Thank you!
