Nice idea, here's the implementation.  It looks really scary if the reparented 
widget isn't addTabbed to the tabwidget, though.  I've tested this in single 
and tabbed mode by hacking Kopete to install some extra .desktop files for 
some plugins.

The one other thing to do would be to change the content margins on widgets 
when they are inserted in single mode.  At the moment the Kopete plugin 
config widgets have fat borders to make them look nice in a tabwidget.  We 
could change this statically in the config widgets themselves, but that is a 
bit of a shame because the widget doesn't know how what it is being parented 
into.  But no white magic occurs to me as the KCModuleProxy is deliberately 
opaque.

I'm not thinking about that now :).
