[RequiresModule] should be able to be specified multiple times

[cward85]

Should be able to use the [RequiresModule] attribute on a recipe multiple times so you can make a recipe require multiple crafting tables in the room for it to work.

Currently you get a compilation error "Duplicate 'RequiresModule' Attribute" when trying to add that attribute multiple times.

This works as designed and hence is not a bug, it however would make for a good improvement - I hence moved it to the ModKit repository whose issue tracker can be used for modding related improvement suggestions. (Including such that are not directly related to the ModKit)
