[Plugin: Visitor Country] Getting IP through proxy using HTTP_X_FORWARD_FOR

We ran into an issue with one of our servers. We believe in your LoadVisitorData() function, the $_SERVER variable ‘HTTP_X_FORWARD_FOR’ should be ‘HTTP_X_FORWARDED_FOR’ ?

Also, some servers will use HTTP_CLIENT_IP. And some configurations will return a list of IP addresses. One of our senior developers submitted this snippet, which would solve all these problems;

// Get the visitor IP
$ip=$_SERVER['REMOTE_ADDR'];
if (!empty($_SERVER['HTTP_CLIENT_IP'])) {               // check ip from share internet
	$ip=$_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {   // to check ip is pass from proxy
	$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
$ips = explode(",", $ip);
$this->mIP=$ips[0];

Please can this or similar be incorporated in your next release?

Many thanks!
