	Allow clients to specify that they want to be ended last (this mainly
	matches the Phase2 of SaveYourself in XSMP). The server doesn't use
	this information yet.

	* gnome-session/gsm-client.[ch]: (gsm_client_class_init): add new
	do_last argument to END_SESSION_RESPONSE signal
	(gdm_client_end_session_response): add do_last and use it
	* gnome-session/gsm-marshal.list: updated for new signature
	* gnome-session/gsm-manager.c: (on_client_end_session_response): add
	do_last parameter, unused for now
	* gnome-session/gsm-dbus-client.c: (handle_end_session_response): pass
	FALSE as do_last
	* gnome-session/gsm-xsmp-client.c:
	(save_yourself_phase2_request_callback): pass TRUE as do_last since
	that's what the phase2 is
	(interact_request_callback): pass FALSE as do_last
	(interact_done_callback): pass FALSE as do_last
	(save_yourself_done_callback): pass FALSE as do_last
