/**
 * update_dolphin is a system function for Dolphin.php . You need to specify the function to print errors, if they happen. update_dolphin requires $_REQUEST['act'] to be set to 'upload-new' or 'download-new', and returns NEED_UPLOAD if it needs to show the upload form (it happens if it cannot download the archive from site). The upload form must contain an input field with name "files[]". If all is ok, returns TRUE, otherwise returns string, containing error description or special NEED_UPLOAD. You need to check for TRUE using === operator.
 *
