Fix issues with recipe API

Quellcode durchsuchen 
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.

Also adds some validation regarding Materials passed to RecipeChoice
being items.
