	Make the panel more robust when the object/applet/toplevel list
	contains incorrect data.
	Most probably fixes bug #137308.

	* panel-gconf.[ch]: (panel_gconf_value_strcmp): new, to strcmp strings
	in GConfValue
	* panel-profile.c: (panel_profile_save_id_list): make sure there is no
	duplicate element in the list when saving it
	(panel_profile_remove_from_list): remove all occurrence of the id in
	the list (and not only the first one)
	(panel_profile_load_toplevel): stop monitoring the gconf dir if
	there's an error
	(panel_profile_load_object): ditto
	(panel_profile_toplevel_id_list_notify): make sure there is no
	duplicate element in the list we get, so we don't add twice the same
	toplevel
	(panel_profile_object_id_list_notify): ditto, for the objects
	(panel_profile_load_list): ditto
	* panel-util.[ch]: (panel_g_slist_make_unique): new, to remove
	duplicate elements in a list

	* main.c: (main): updated, stop monitoring a gconf dir
	* panel-session.[ch]: (panel_session_init): we don't need the argument
	anymore
