  #1368247: make set_charset/MIMEText automatically encode unicode _payload.

  Fixes (mysterious, to the end user) UnicodeErrors when using utf-8 as
  the charset and unicode as the _text argument.  Also makes the way in
  which unicode gets encoded to quoted printable for other charsets more
  sane (it only worked by accident previously).  The _payload now is encoded
  to the charset.output_charset if it is unicode.
