Return the original key in the hash table if requested.

2001-10-10  Federico Mena Quintero  <federico@ximian.com>

	* pcs/cal-factory.c (lookup_backend): Return the original key in
	the hash table if requested.
	(backend_last_client_gone_cb): Use lookup_backend() so that we
	have the URI mangling done for us.
	(impl_CalFactory_open): The type should be GtkType *, not GtkType!
