	* cal-client/cal-client.[ch]:
	(cal_client_init): create a WombatClient when creating a CalClient
	object, so that we can receive authentication notifications from
	the wombat
	(cal_client_destroy): destroy the WombatClient object when dying
	(cal_client_set_auth_func): new function to set the authentication
	function to be called when a password is required by the calendar
	server (through the WombatClient object)
	(cal_client_get_free_busy): new function for calling the new IDL
	method Cal::getFreeBusy
