Recipe categories - for easier modding

[AVE]

How about adding new Def - RecipeCategoryDef? It is something like 'recipe grouping' and you can add this category to building definition - and it then can produce items from all the recipes in that group.

Simple example - define 'Cooking' category and you can extend cooking stove (which will use that category instead of recipe list) without overwriting it in your mod by simply adding new meal recipes with that category.

Well disregard this, TIL about "recipeUsers" tag in recipes and items.
