	Use gnome-power-manager to implement suspend/hibernate.
	Based on patch by Ray Strode <rstrode@redhat.com>
	Fix bug #347970

	* panel-power-manager.[ch]: new files
	* Makefile.am: add new files
	* panel-logout.c: (panel_logout_init) connect to the power manager
	(panel_logout_destroy): unref the power manager
	(panel_logout_response): keep a ref to the power manager since we need
	it for this function, don't use GDM to hibernate since it has the nasty
	side-effect of loggint out the user..., implement suspend
	(panel_logout_new): add buttons to suspend and hibernate

	* panel-enums.h: reindent one line
	* panel-menu-items.h: ditto
