* Field for uploading single or multiple files of all types, including images.
* <b>NOTE: this Field will call write() on the supplied record</b>
*
* <b>Features (some might not be avaliable to old browsers):</b>
*
* - File Drag&Drop support
* - Progressbar
* - Image thumbnail/file icons even before upload finished
* - Saving into relations
* - Edit file
* - allowedExtensions is by default File::$allowed_extensions<li>maxFileSize the vaule of min(upload_max_filesize, post_max_size) from php.ini
*
* @example <code>
* $UploadField = new UploadField('myFiles', 'Please upload some images <span>(max. 5 files)</span>');
* $UploadField->getValidator()->setAllowedExtensions(array('jpg', 'jpeg', 'png', 'gif'));
* $UploadField->setConfig('allowedMaxFileNumber', 5);
