[gnome-bluetooth] Add summary page to the moblin applet

[Tambet Ingo <tambeti src gnome org>]

commit e3189eb136f7335e057ba02c8a4572e761955545
Author: Tambet Ingo <tambet gmail com>
Date:   Tue Dec 8 15:53:25 2009 +0200

    Add summary page to the moblin applet
    
    Show the page only if any of the plugins provides widgets for the created
    device.
    Fix a bunch of assertion failures on exit caused by not handling multiple
    dispose() calls.
