c4975cc4 Create Application::on() method to add an event listener

Discussion
----------

Add method Application::on($eventName, $callback, $priority)

Simplify PR #435

This method is a shortcut to add a listener to the event dispatcher.

``` php
<?php
use Symfony\Component\Security\Http\SecurityEvents;

$app->on(SecurityEvents::SWITCH_USER, function ($event) {
    // ...
});
```

Can you add some useful examples in the documentation before I merge this PR? Thanks.

Which part of the documentation would be the most relevant ?

I can write a cookbook on how to send an email when someone login to the application.
