A new method for Recipe objects to get a Recipe from an ArrayList of ItemStacks. The position of the ItemStack in the Array would correlate to the position of the ItemStack in the Recipe's shape.

For Shaped vs Shapeless Recipes, could either:

• Use ShapedRecipe.fromArray() and ShaplessRecipe.fromArray()
  or
• Use Recipe.fromArray() and match ShapedRecipe first. If no ShapedRecipe matches, try to match a ShapelessRecipe.
