Qt radio boxes

I've tried to fix the "if self.widget" stuff in qtgui; still not sure
whether it's correct, but at least now test_place.py runs. (It was
having problems with radio groups, I think.) But the radio groups
still don't work properly. Could someone who knows more about PyQt
perhaps take a look? (The Anygui cvs server is down for maintenance, I
think, so I can't get my changes checked in right now -- but the gist
of it was to add an "if self.widget"-test to setValue() for
RadioButtonWrapper.
