Add controller's implemented interfaces to its shared event manager default identifiers

[SwissEngine]

Apparently, from the shared manager, it is not possible to attach a callback to a controller (dispatch event) from an interface id it implements.

I simply added the list of the implemented classes to the identifiers. This adds the possibility to do this:

// Module.php - this was never triggered
$eventManager->getSharedManager()->attach(LambdaControllerInterface::class, 'dispatch', [
    $this, 'myCallback'
]);

// MyController.php
class MyController extends AbstractActionController implements LambdaControllerInterface
{
}

I am not an expert on the event managers, waiting for some feedback before adding some tests.

@SwissEngine can you please rebase this? There's an unrelated commit in it. Additionally, tests required.

[Ocramius]

May just if ($instanceOf = class_implements($this)) { instead

[SwissEngine]

@Ocramius rebased and changed, will write tests today

end with
