This skips the default behavior to instantiate `Command` that cannot simply be instantiated. The respective commands have to be registered by other means.

Hi,

I found a case where a fatal error happen when trying to set a value in a form field with a malformed name.

```
Fatal error: Call to a member function setValue() on a non-object in /home/pierreyves/projects/symfony2/symfony/src/Symfony/Component/DomCrawler/FormFieldRegistry.php on line 128

```

In this case, `FormFieldRegistry::getSegments('foo[bar')` method is called and it will return `array('foo')` only. Therefore the return of `FormFieldRegistry::get('foo[bar')` returns an array instead of a `FormField` and so the `setValue()` call happen on the array which leads to the fatal error.

I tried to fix that. I don't know if it's the best way to do this so, as always, comments are welcome.

[Form] corrected interface bind() method defined against in deprecation ...

...notice

The 'bind' method is defined against `FormInterface` not `FormConfigInterface`. This corrects the deprecation notice in the `Form` implementation.
