Userid fetch for upload.php in ReportNP.html

Created a function InvokeReturnUserID() in hh.js which return the
userid. Now in ReportNP.html, I am calling that function inside init(),
and stores the value returned by InvokeReturnUserID() into a local
variable, which I am passing to the URL as
"http://www.hubclone.com/components/com_hamlethubmobileapp/upload.php?hh_userid=userid".
