'origbody' Source no longer used by Mailhandler module

mailhandler update 6207 has changed the 'Body' (origbody) importer mapping source to 'Body (HTML)' (body_html).

However, mailcomment continues to use the 'origbody' in multiple places in mailcomment.module and mailcomment_default/mailcomment_default.feeds_importer_default.inc

 $grep -R origbody *
mailcomment_default/mailcomment_default.feeds_importer_default.inc:61:            'source' => 'origbody',
mailcomment.module:454:  $identifier = _mailcomment_get_signature(rawurldecode($item['origbody']));
mailcomment.module:555:        $message['origbody'] = _mailcomment_filter_basic($message['origbody']);
mailcomment.module:560:        $message['origbody'] = _mailcomment_filter_aggressive($message['origbody']);
plugins/authenticate_plugin/MailcommentAuthenticate.class.php:15:    $identifier = _mailcomment_get_signature(rawurldecode($message['origbody']));

I think this can be fixed by changing each instance of origbody to body_html.
