Update dependency_injection.rst because it has an error.

The line: $sc->register('listener.router', 'Symfony\Component\HttpKernel\EventListener\RouterListener') ->setArguments(array(new Reference('matcher'))) ; is wrong, because the Symfony\Component\HttpKernel\EventListener\ResponseListener has two mandatory arguments; an instance of Symfony\Component\Routing\Matcher\UrlMatcher (or RequestMatcher), and an instance of RequestStack; so, we need to add the line: $sc->register('request_stack', 'Symfony\Component\HttpFoundation\RequestStack'); And change the registration of listener.router on this form: $sc->register('listener.router', 'Symfony\Component\HttpKernel\EventListener\RouterListener') ->setArguments(array(new Reference('matcher'), new Reference('request_stack'))) ;
