[gpm] Move to mail.gnome.org

[Richard Hughes <hughsient gmail com>]

First, sorry for all the spam in one day.

You might have noticed that I've moved the list (heh), but not yet the
archive. Anyone got any ideas on how to move the sourceforge archive to
the gnome archives? Else I can include a link on the g-p-m pages to
"old" and "new", but I really don't want to do that if at all possible.

Richard.
