Dirty Glass is uncraftable

Dirty Glass is the only quark:exclusion recipe in the mod. Variant chests (which use the different mixed_exclusion type) work okay, including the recipe that lets you craft vanilla chests with mixed wood. Hmm.

Omg lol, I was expecting this to be crazy to debug but nah, ExclusionRecipe.ShapedExclusionRecipe was just super buggy 😄
