[gtk+/wip/gbsneto/other-locations: 3/3] filechooserwidget: use places view to manage fixed devices

    filechooserwidget: use places view to manage fixed devices
    
    Previous patch modified places sidebar widget to stop handling
    fixed devices by adding an "Other Locations..." item. Up to now,
    however, these changes are isolated from each other since the
    bundled file manager widgets ignore the sidebar requests for
    external management of fixed devices and networks.
    
    To fix that, make the file chooser widget be aware of the
    GtkPlacesSidebar::show-other-locations signal and, when requested,
    show places view to manage the fixed devices and networks.
