This PR is an extract of the new Notifier component. It's a default template to send standardized emails with the Mailer component, which can be used independently of the Notifier component.

Such emails look like the following:

<img width="618" alt="image" src="https://user-images.githubusercontent.com/47313/65018883-694cb780-d92a-11e9-940a-875ea68f9e5d.png">

More info on SpeakerDeck (be warned that names have change since my presentation): https://speakerdeck.com/fabpot/symfony-notifier?slide=7

It requires Twig 1.12 which should be released later this week.

Usage example:

```php
$email = (new NotificationEmail())
    ->from('fabien@example.com')
    ->to('fabien@example.org')
    ->subject('My first notification email via Symfony')
    ->markdown(<<<EOF
There is a **problem** on your website, you should investigate it right now.
Or just wait, the problem might solves itself automatically, we never know.
EOF
    )
    ->action('More info?', 'https://example.com/')
    ->importance('high')
    //->exception(new \LogicException('That does not work at all...'))
;
```

Instead of `markdown()`, you can also use `content()` for simple emails.

Note that you can use Inky tags in the content:

```php
$email = (new NotificationEmail())
    ->from('fabien@example.com')
    ->to('fabien@example.org')
    ->subject('My first notification email via Symfony')
    ->markdown(<<<EOF
There is a **problem** on your website, you should investigate it right now.
Or just wait, the problem might solves itself automatically, we never know.

Some Title
==========

<center>
    <button href="https://example.com/">Go?</button>
</center>

EOF
);
```

There is also the concept of a theme. By default, it uses the `default` theme,  which is an alias for the `zurb_2` theme.

You can use `setTheme()` to override the theme for a given instance, or override the themes globally via the following config in `twig.yaml`:

```yaml
twig:
    paths:
        templates/email: email
```

Then, create `templates/email/default/notification/body.html.twig` and `templates/email/default/notification/body.txt.twig`. Extends the existing template via `{% extends "@!email/default/notification/body.html.twig" %}` (note  the `!`).
