Added a "//" in front of the replacement holder in phartemplate.php (and adjusted PHPArchive.php accordingly). This removes a misleading error message in IDEs that treat phartemplate.php as an "actual" PHP file;

Also includes a fix for the data dir, which should in both cases be 4 levels above PHPArchive.php's folder.
