    Make location bar more reactive, part 2: navigation bar
    
    Followup to the last commit: The location bar of the inactive pane now
    has an insensitive apprearance, but is in fact clickable/focusable. A
    click makes the corresponding pane active via the focus-in event of
    the entry widget.
