    connection: Use inheritance instead of delegation
    
    We used to use delegation almost exclusively, but since we started to apply
    templates, inheritance has been creeping in more and more. By now, from all
    our classes that provide a UI, about half inherit from Gtk.Widget while the
    other half uses a .widget delegate. The resulting inconsistency is getting
    rather annoying, so say good-bye to delegation and embrace inheritance ...
