Added send_pgp_mime.Mail.encodedMIMEText() for unicode handling.

Now be-handle-mail handles examples/unicode without crashing
  cat examples/unicode | ./be-handle-mail -o -l -
But the output email is encoded in base64:

MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64

This is perhaps the best we can get out of python < 3.1/2.7, see
