finds the client data for a client (cal_opened_cb): update the query

2004-03-26  JP Rosevear <jpr@ximian.com>

	* gui/e-cal-model.c (find_client_data): finds the client data for
	a client
	(cal_opened_cb): update the query
	(add_new_client): return client data
	(e_cal_model_add_client): add the client immediately no matter
	what, and possibly wait for it to open
	(remove_client): guard against NULL query
	(e_cal_model_remove_client): use find_client_data
	(e_cal_model_dispose): guard against a NULL query
