It would be nice to have a simple JEI tab that tells you what you can get by opening a specific satchel (Egg Box, Book Satchel, Old Luggage, Iron Box...).

It could be either like JER's dungeon tab with a huge table per box, or like IC2 Scrapboxes (or like a simple machine like ExU2's Resonator).

Thanks to Mrbysco's contribution in the recent commit, JEI is now supported.
