new method.

2002-04-05  Rodrigo Moya <rodrigo@ximian.com>

	* pcs/cal-backend.[ch] (cal_backend_get_query): new method.

	* pcs/cal-backend-file.c (cal_backend_file_get_query): new method.

	* pcs/cal.c (impl_Cal_get_query): call the CalBackend's implementation
	instead of calling query_new directly.

	* pcs/query.[ch]: fixed headers.
