auth/db/auth.php - fewer queries against the ext db

Browse Source 
Previously sync script would query the ext db once for each field that
might be wanted (repeated for each user).  Changed to query once for each
user.

Originally by Peter Bulmer <peter.bulmer@catalyst.net.net>
Somewhat adapted by Martin Langhoff ;-)
