Item12952: Partial fix for email wizard.

missing elsif caused fallthru to failure even when configuration worked.

Also remove the PREFORMAT: tag so that the debug log is readable.

There are still some issues.   It doesn't actually apply any
configuration changes.  Testing with gmail.  587 Submission with STARTTLS works
fine,  but configuration is left at hostname, no port,  and SMTP not
STARTTLS.

Also the code that masked passwords to avoid shoulder surfing while
configuration is exposed has been lost,  so passwords are stored in
plain text.    This is lame,  we probably ought to store using some
basic encryption.  But the masking was better than nothing.
