add/recipes placeholders

[Jaimss]

resolves #28

Questions:

• how should an invalid namespaced key be handled? right now I return "invalid recipe", is that ok?
• for listing recipes, it's really ugly and there's really no use case it seems. maybe it should be removed
• IntelliJ changed around imports. is that ok?
• Version change required?

@Jaimss do you think you could update this?

[Jaimss]

Yea I'll try to update it when I get a chance.

that should have it working still
i can test it again later if you want but it was just resolving a merge conflict so hopefully nothing broke lol
