Recognize recipes containing themself

[Bananeweizen]

What problem are you trying to solve?

I accidentally included a recipe in itself. The StackoverflowError should be avoided, and a clear error message should be presented.

Describe the solution you'd like

Check any nested recipe to not be in the "already seen" set at the beginning of the initialization request.
