New login/logout events in 5.2

[jszobody]

Laravel 5.2 changes a bunch of events including auth.login and auth.logout to event objects.

• auth.login -> Illuminate\Auth\Events\Login
• auth.logout -> Illuminate\Auth\Events\Logout

For now I've just dropped this into my own AppServiceProvider so I can keep moving forward with my 5.2 upgrade:

$app['events']->listen(\Illuminate\Auth\Events\Login::class, function($event) use($app){
    $app['security.token_storage']->setToken(new LaravelToken($event->user));
});

$app['events']->listen(\Illuminate\Auth\Events\Logout::class, function() use($app){
    $app['security.token_storage']->setToken(new LaravelToken(null));
});
