[Config] Numerical keys for prot. arrays if useAttributeAsKey is set
Bug fix: not sure
Feature addition: not sure
Backwards compatibility break: not sure
Symfony2 tests pass: [](http://travis-ci.org/asm89/symfony)
License of the code: MIT
When using an array node with children of prototype array and `useAttributeAsKey`, using numerical values for the keys throws an exception. For example (`useAttributeAsKey('id')`):
``` php
<?php
// works
array (
'thing' => array(
array('foo', 'bar', 'id' => 'a')
)
);
// works and is the same as above
array (
'thing' => array(
'a' => array('foo', 'bar')
)
);
// works
array(
'thing' => array(
array('foo', 'bar', 'id' => 42), array('baz', 'qux', 'id' => 1337),
),
);
// works with this patch and is the same as above
array(
'thing' => array(
42 => array('foo', 'bar'), 1337 => array('baz', 'qux'),
),
);
```

Could this be fixed by changing [PrototypedArrayNode](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Config/Definition/PrototypedArrayNode.php#L255)
`$k = $v[$this->keyAttribute];` -> `$k = (string) $v[$this->keyAttribute];`

I tried it and the test I added still fails. The code change you propose doesn't execute because `if (!isset($v[$this->keyAttribute]) && is_int($k))` will still evaluate to true.
