Item data editor

If you have ever tried to change a vanilla loot table like fishing or bartering, you will know what I am talking about; some mod elements don't have the ability to apply data to items, like in procedures, here is a list of the elements that need it (in order from most to least necessary):

• loot table, for recreating vanilla loot.
• recipe, for making and using more specific items like, water bottles.
• trade, for adding data traded items
• mob, for adding data armor and weapons.
• block, plant, and mob all need it for data drops (this can be done with loot if the first one is added).
