Title: Make WP_Session Behave More Like an Array

Implement `Iterator` and `Countable` so the Session object behaves more fully like an array (ala the real `$_SESSION`).

Might be an easier shortcut here to extend [`ArrayIterator`](http://php.net/manual/en/class.arrayiterator.php), but you can't guarantee it exists with PHP < 5.3.
