We have a new "last_calendar_gone" signal that Wombat can use to terminate

2000-04-16  Federico Mena Quintero  <federico@helixcode.com>

	* pcs/cal-factory.h (CalFactoryClass): We have a new
	"last_calendar_gone" signal that Wombat can use to terminate
	itself properly.

	* pcs/cal-factory.c (cal_factory_class_init): Register the
	"last_calendar_gone" signal.
	(backend_destroy_cb): Emit the "last_calendar_gone" signal instead
	of killing the factory.

	* pcs/Makefile.am: Added $(CORBA_GENERATED) to BUILT_SOURCES.
	(INCLUDES): Make the log domain be "wombat-pcs".
