valid-config-key? should include check that keyword has a namespace

[Rick Moynihan]

I've just tried to put a spec on a datastructure that contains a system map, and thought I'd use the function ig/valid-config-key?, however it appears it doesn't test for the keyword also being a namespaced keyword.

Might it be worth tightening the test here?

 (or (keyword? key) (composite-key? key)))

Yes, that sounds like a good idea.
