CustomCrafting causes different ItemsAdder items can be merged in grindstone

[AllayBreeze]

What happened?

If both CustomCrafting and ItemsAdder are installed, different IA items that have the same material types, or an IA item and a same material vanilla item, can be merged in grindstone.

For example, use IA to create "Copper Sword" and "Tin Sword", both are using IRON_SWORD as material. If CustomCrafting is installed, a copper sword and a tin sword can be put into the grindstone together, and output an item that has the same data as one of them; or put a copper sword and a vanilla iron sword, which is also possible and can output one of them.

However if the server only has IA, different IA items are not able to be put into a grindstone together even they're made by same material. So I think it's a confict between CustomCrafting and IA.

How can the bug be reproduced?

1. Install CustomCrafting and ItemsAdder together.
2. Create two different IA items with the same material.
3. Get them and put into a grindstone.

Expected Behaviour?

These two items should not be able to be put together into a grindstone, and output an item with the same data as one of them.
