[For 1.6] ProfileComments

[Aquilez]

Right! I installed "Referral in profile" (or Show Refer) today, and yes, when you visit your profile (http://localhost/mybb/member.php?action=profile) it shows all users WITOUTH a referrer.

Is the same with ProfileDesign, they don't check the $GET vars
To fix it, find:

	$query = $db->simple_select("users", "username, uid", "`referrer` = '".$mybb->input['uid']."'");

Replace with:

	if(!empty($mybb->input['uid']))
	{
		$uid = intval($mybb->input['uid']);
	}
	else
	{
		$uid = $mybb->user['uid'];
	}

	$query = $db->simple_select("users", "username, uid", "`referrer` = '".$uid."'");

I don't know why are posting this here. They don't work even with ProfileComments uninstalled.
