add hidden pref 'reqrite_first_from'

'0' or '1'. This works around a limitation of some servers with
'overly-liberal parsers'. When this is turned on and the Content-
Transfer-Encoding is set to 8bit or 7bit, in a message body starting
with 'From ' the 'From ' will become '=46rom ' and the
Content-Transfer-Encoding will be changed to Quoted-Printable. When it
is turned off no such modification will be made but it is very likely
that an MTA will convert the 'From ' to '>From '. See RFC 4155 for
further details. Default value is '1', turned on.
