[1.7.10] Fix for Auto-Login

[kai]

If the auto-login is not working on your 1.7.10 installation of 4images please use this fix:

in includes/session.php

find

$this->set_cookie_data("userpass", $this->user_info['user_password']);

and replace with

$this->set_cookie_data("userpass", md5($this->user_info['user_password']));
