Akamai Netstorage does not support ftp_chmod

If you make use of the service Netstorage from Akamai you are not allowed with the ftp user to set the chmod causing the upload of a file to fail.

I solved it temporarily in the file: ftp.inc on line 82 cause Akamai forces the correct settings on ftp so for the net storage the call is unnecessary.

private function setMode($filename, $mode) {
    
//    if (!ftp_chmod($this->ftpStream, octdec(str_pad($mode, 4, '0', STR_PAD_LEFT)), $filename)) {
//      throw new StorageException();
//    }
}

A good idea is to check if the the action is possible or an optional setting in the configuration.
