    [MeeGo] MeeGo panel is created via Mono Addins
    
    The MeeGoPanel object is instantiated via the PostInitializeGtk
    hook through Mono.Addins plumbing. This ensure we can respond to
    Mutter Moblin's toolbar DBus activation request. We can populate
    it later when the rest of the MeeGo service has started up.
