    network: Make the history dialog use a headerbar
    In order to start moving towards the new redesigned Network
    panel [1], it is necessary to make the dialogs use a headerbar.
    Currently, however, they don't, making the dialog sinconsistent
    with the rest of the panels, and the GNOME desktop as a whole.
    Fix that by setting the headerbar to the History dialog.
