Currently, the tinker recipe system is really good, but can only craft single items (AFAIK). This should be altered so that a recipe can create more than one product (eg. 10 missiles coming out of a recipe, rather than 1).

Would also be great if this allowed byproducts as well, but not absolutely necessary (that would be more suited to a standard crafting system if one ever gets built in the future for modularity purposes)
