	* applet.c, extern.[ch], launcher.c, panel-widget.[ch], panel.c,
	  session.c:  Remember the last known config for applets, add a
	  signal (quite hackish) to figure out when an applet is about to
	  die.  If an applet dies unexpectadly (without being removed by user
	  or calling unregister_us), then display a dialog box and allow the
	  user to readd the applet with it's last saved settings.  This
	  should reduce the "where did my <insert name of applet>" go and
	  how do I get it back.
