* At the moment, only activity modules are supported. The method generates link
* to the module's file grade.php with the parameters id (cmid), itemid, itemnumber,
* gradeid and userid. If the grade.php does not exist, null is returned.
*
* @return moodle_url|null URL or null if unable to construct it
