    trash-bar: Add link to autodelete settings
    
    Nautilus currently provides no indication that GNOME Settings allows
    users to configure automatic emptying of the trash. This commit adds
    a button to the trash bar which links to the corresponding configuration
    panel in Settings, allowing users to configure autodelete.
