    filechooserwidget: use GtkPlacesView to display devices
    
    Following the previous commits, make GtkFileChooserWidget use
    the brand new GtkPlacesView to display local drives when "Other
    Locations" is clicked.
    
    For the sake of testing, GtkPlacesView::local-only property is set
    to FALSE.
