I guess it's pretty common to want a single "changed" signal and a
single fetch to get what (if anything) is the current choice of a group.
I fiddled around the other day with a menu of radio items for some
database choices like that.  But perhaps there's too many variations to
share much code.

So the "active" value can be a property?  I guess that'd be a fresh type
for the collection thingie every time.  Might be easier if it was just a
scalar and don't bother telling gtk about the range of values (check
them separately if desired).
