Set recipe quality

[FluidNatalie]

The property RecipePrototype:can_set_quality fixes the quality of a recipe to normal. An additional property RecipePrototype:recipe_quality (you pick the name) would be create so that you can have fixed recipes of different qualities.

This would allow you to set recipes with higher quality ingredients and have them result in normal output in a higher amount:
Normal Iron Plate + Normal Iron Gear = Normal Belt
Uncommon Iron Plate + Uncommon Iron Gear = 2 Normal Belts

Currently this works but all the recipes are in the normal category.
