Updates - using info in .mh_profile for how the asimap server behaves.

[scanner]

* It would be great if auth.py read ~/.mh_profile to get things like the
 maildir.  The vars "Path" (the maildir), "MailDrop" (the mbox spool
 file to inc from), and "Flist-Order" (an ordering for mailboxes) might
 be useful.

Do not lose recommendations from Bill Janssen ([email protected]) ..

We probably will add support for local unix accounts again so remember these comments.
