Fixed int typecasting of limit parameter in DB_active_rec.php

If an empty string was passed, the typecast was changing it to 0. This
produced "LIMIT 0" which returned no results. This must be a bug and not
a feature because there are other params after limit in both
$this->db->limit and $this->db->get.
