Make the mail code detect USING_DEBUG_EMAIL_SERVER which if set to

true and EMAIL_HOST and EMAIL_PORT is set to localhost:1025 will turn
on debugging which essentially makes it send emails; also added
instructions for starting the debugging SMTP server bundled with
Python

  python -m smtpd -n -c DebuggingServer localhost:1025
