	First part of smoothing the panel slide-in on login.
	Part of bug #554343.
	Patch by Ray Strode <rstrode@redhat.com>, with a few minor bug
	fixes/changes from me.

	We delay the slide-in until all panel objects are loaded.

	* applet.[ch]: (panel_applet_queue_initial_unhide_toplevels): new
	(panel_applet_stop_loading): new, when an object has stopped loading,
	we look if we should queue an unhide
	(panel_applet_load_idle_handler): put the applet that is being loaded
	in the list of applets loading, and call panel_applet_stop_loading()
	when it makes sense
	(panel_applet_load_queued_applets): unhide the panels if there's no
	applet to load
	* panel-applet-frame.c: (panel_applet_frame_activated): consolidate
	freeing stuff in case of error, and call panel_applet_stop_loading()
	* panel-toplevel.[ch]: (panel_toplevel_attach_to_widget): an attached
	toplevel (ie, drawer) should not have an initial animation
	(panel_toplevel_initially_hide): don't queue an unhide here, but still
	update the struts
	(panel_toplevel_queue_initial_unhide): new
