Add a login event for login counter and flash message for login success.

[dereuromark]

The normal login code is not fired/executed at all for hybrid auth login:

/**
 * @return \Cake\Http\Response|null
 */
public function login()
{
    if ($this->request->is('post')) {
        $user = $this->Auth->identify();
        if ($user) {
            unset($user['password']);
            $this->Auth->setUser($user);
            $this->Users->loginUpdate($user);

            $this->Flash->success(__('You are now logged in'));
            return $this->redirect($this->Auth->redirectUrl());
        }
        $this->Flash->error(__('Login or password was not correct'));
    }
}

As such no flash message for successful login or login counter update can happen right now.

This adds the missing event to be able to enable this (to sync with normal post form login).

Please change [$user] to ['user' => $user] for easier accessibility.

What do you mean?
This is passed as argument, so there is no key here anyway.

The docs I added show it used as

public function updateUser(Event $event, array $user)
{
    $this->loginUpdate($user);
}

protected function loginUpdate(array $user) 
{
    return (bool)$this->updateAll(['last_login' => new FrozenTime()], ['id' => $user['id']]);
}

Yes it's passed as argument but using key also allows accessing it as $event->getData()['user']. I have done similar when 'HybridAuth.newUser' event is dispatched from the authenticate class so let's stay consistent.

Ah, I see both used in core, I guess for debugging etc it is easier to have the assoc key? OK

[dereuromark]

Done :)
