added piece of code for demographics

To enable demographics in Analytics i had to edit plugins/NKgoogleanalytics.php find the following lines:

$tk .= "ga('create', '" . $nkweb_id. "', '" . $Domain . "'); \n";
$tk .= "ga('send', 'pageview'); \n";

and add this

$tk .= "ga('require', 'displayfeatures'); \n";

in between so it became:

$tk .= "ga('create', '" . $nkweb_id. "', '" . $Domain . "'); \n";
$tk .= "ga('require', 'displayfeatures'); \n";
$tk .= "ga('send', 'pageview'); \n";

Are you incorporating this soon?
