Fixed most of the issue in head but not like you expected to.

If you clone an ArrayIterator you also clone its reference thus the
described behavior below is correct.

If you clone an ArrayObject you clone the array, too. However the
behavior is not completely correct yet.

Description:
------------
ArrayIterator does not clone itself

Reproduce code:
---------------
$a = new ArrayIterator();
$a[] = 1;

$b = clone $a;

var_dump($a[0], $b[0]);
$b[0] = $b[0] + 1;
var_dump($a[0], $b[0]);


Expected result:
----------------
int(1)
int(1)
int(1)
int(2)


Actual result:
--------------
int(1)
int(1)
int(2)
int(2)
