revert to old method (only use XOVER if OVER is supported.)

2000-10-04  Chris Toshok  <toshok@helixcode.com>

	* providers/nntp/camel-nntp-utils.c (camel_nntp_get_headers):
	revert to old method (only use XOVER if OVER is supported.)

	* providers/nntp/camel-nntp-store.c
	(camel_nntp_store_get_overview_fmt): handle the case where the
	OVER extension isn't listed but LIST OVERVIEW.FMT works (again,
	INN 2.2).  enable the OVER extension in this case.
