Allow item stacks as input for recipes

* 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
