SITE_URL constant incorrect on windows servers

[Uranium235]

Even though the root directory and https issues have been fixed/addressed in the development branch, windows servers will still not function properly as dirname() return a backslash instead of a forward slash for the document root on windows systems.

fix:

$protocol = 'http';
if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] && $_SERVER['HTTPS'] != 'off')
 $protocol .= 's';
$directory = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
define('SITE_URL', $protocol.'://'.$_SERVER['HTTP_HOST'].$directory);
