Update LookingGlass.php

http prefix check is too generous allowing for http to appear anywhere

Yeah. I think that line should be something more along the lines of:

if (stripos($url, 'http://') !== 0 && stripos($url, 'https://') !== 0) {
     // Make HTTP URL
}

It may not matter though since the host is extracted from the URL not long after the "HTTP" protocol part is added to it if deemed necessary by this check.
