- CraftItemEvent
	- added the following:

		- getOutputs()
		- getRepetitions() (tells how many times a recipe was crafted in this event)
- Recipe interface:
	- Removed getResult() (individual recipes may handle this differently)
- CraftingRecipe interface
	- removed the following:
		- matchItems()
		- getExtraResults()
		- getAllResults()
	- added the following
		- getResults()
		- getIngredientList() : Item[], which must return a 1D array of items that should be consumed (wildcards accepted).
