* @param bool $b64encode true to base64encode file data (default false)
* @param bool $ignore_empty true to not throw exception if form fields doesn't contain a file (default false)
* @param int $max_kb maximum size allowed for upload (default unlimited)
* @param array $ok_types if array is provided, only files with those Extensions will be allowed (default all)
* @return FileUpload object (or null if $ignore_empty = true and there is no file data)
