Subject: [PATCH] Fix issues with recipe API
Improves the validation when creating recipes
and RecipeChoices to closer match what is
allowed by the Codecs and StreamCodecs internally.
Adds RecipeChoice#empty which is allowed in specific
recipes and ingredient slots.
Also fixes some issues regarding mutability of both ItemStack
and implementations of RecipeChoice.
