auth/authenticate: Much done!
    Fixed immediate failure if user not in DB (now sets user to None to give
    it the chance to pulldown).
    Now writes the user to the DB if a user object is returned.
    Fixed simple_db_auth raising if the user is not in the DB. It now returns
    None, again, to give chance to pulldown.
    Fixed importing modules - the auth dir is not in sys.path so there are
    import errors. Did some foo (a LOT of magic) to get the auth dir in
    sys.path.

auth/ldap_auth: Fixed missing import.
auth/guest_auth: Added new auth module, guest. This is more of a toy.
    It auths guest/guest and also returns a new user which is written to the
    DB - so it's like a user pulldown module.

userdb/users.sql: Fixed rolenms allowed - these did not match caps.Role.
