decode newsgroups header into a list of newsgroups.

2004-03-22  Not Zed  <NotZed@Ximian.com>

        * camel-mime-utils.c (camel_header_newsgroups_decode)
        (camel_header_newsgroups_free): decode newsgroups header into a
        list of newsgroups.

        ** See #55887.

        * providers/nntp/camel-nntp-summary.c (camel_nntp_summary_check):
        NOOP if we're offline.

        * providers/nntp/camel-nntp-store.c (nntp_connected): spit a
        warning if we try to do stuff whilst offline, rather than crash.
