Hobbies can give recipes

Summary

None

Purpose of change

Hobbies could give proficiencies but not recipes. This seems like an oversight.

Describe the solution

Copy the hobby proficiency code. Adjust. Test. Adjust.

Describe alternatives you've considered

All the people I would beg have given their lives over to minecraft for immediate future. Must attempt on ownself first.

Testing

Additional context

[QuillInkwell]

The code wasn't quite working.

I've compiled and tested it with these changes and confirmed the Gracken hobby awarded the recipes.

If you're curious the problem was:
Once you get all the recipe ids you don't want to assign to the profession IDs type they ought to be recipe ids.
If I am reading the code correctly, the has_learned check is redundant here. learn_recipe is already guarded against duplicated entries.
There doesn't seem to be a function called add_recipe. Instead learn_recipe is what you need to use. Which does require fetching the actual recipe object using the id.
But I am pretty new to the code base and C++ in general so take what I say with a grain of salt.

This is a great improvement, well deserved. Way to go!
