nntp: add "newsgroup" parameter and sort grouplist

Using non-hierarchical mailing list names for newsgroups
might confuse traditional newsreader software and perhaps
some humans.  Allow administrators to configure newsgroups
names and hierarchies to their liking.

Sorting the grouplist alphabetically should probably be
done anyways to improve usability for some clients which
won't sort themselves.
