[gnome-screenshot] Implement g_application_activate()

[Michael Catanzaro <mcatanzaro src gnome org>]

    Implement g_application_activate()
    
    GLib-GIO-WARNING **: Your application does not implement
    g_application_activate() and has no handlers connected to
    the 'activate' signal.  It should do one of these.
    
    Also, there's no point in creating the app menu each time we want to
    take a screenshot, so move that here.
