* Create the SlotController and refactor it into the various places
where a crafting grid or crafting output is displayed
* Update the Recipe model to allow each "input" stack to retain the
count indicated in the data file. This required changing how a few
other classes interact with it in order for them to get the full
stack back again for each input (instead of just getting the item
slug)
* Update the ModVersionParser to allow for full stacks to be given
as input and refactored common code out for handling input/output/
tools stacks
