Broken attach file name

[joungkyun]

On SVN trunk revision 1941 or 0.2-beta, attach file name that made with RFC 2231 is broken.

For example, file name encoding with follows,

 filename*0*=UTF-8''%32%30%30%38%30%39%32%36%20%EC%82%AC%EB%AC%B4%EC%8B%A4;
 filename*1*=%2E%6A%70%67

roundcube parsed only filename*1* with follow codes

     else if (!empty($part->d_parameters['filename*0*'])) {
       $i = 0;
       while (isset($part->d_parameters['filename*'.$i.'*'])) {
         $i++;
         $filename_encoded .= $part->d_parameters['filename*'.$i.'*'];
       }
       if ($i<2) {
         $headers = iil_C_FetchPartHeader($this->conn, $this->mailbox, $this->_msg_id, $part->mime_id);

So, I attach patch that fix this problem.
