Fix call by reference for PHP 5.4
Changed cookie encryption to rijndael

Since suhosin disabled srand() by default and CakePHP's Security::cipher()
function uses srand(), the encryption of cookies does not work properly out of
the box.

The cookie encryption is changed to rijndael and mcrypt extension must be
installed.
