IP ranges Upgrade

Hi,

Thanks for this plugin, works fine. I made small upgrade, because I need to allow lot of IP’s. Now I can use ranges of IP’s. Check this, maybe you can include in next update (your original lines are commented):

function allow_ip_addresses( $bool ) {

		$ip_addresses = $this->get_allowed_ip_addresses();

		// if ( in_array( $_SERVER['REMOTE_ADDR'], $ip_addresses ) ) {
			// $bool = false;
		// }

		// return $bool;
		foreach ($ip_addresses as $adres) {
			list($lower, $upper) = explode('-', $adres, 2);
			$lower_dec = ip2long($lower);
			if (isset($upper)) {$upper_dec = ip2long($upper);}
			else { $upper_dec = $lower_dec;}
			$ip_dec = ip2long($_SERVER['REMOTE_ADDR']);
			if ($ret=( ($ip_dec>=$lower_dec) && ($ip_dec<=$upper_dec) )) {
				//echo $ret;
				return false;
			}
		}
		return true;
	}
