error.html.twig should contain a email value

When getting an exception on env PROD it would be nice to have an email to report to.

Current code has [email] instead of a value.

I'm not sure how to fix this as the email value should come from exception.html.twig

```html
<div id="logs">
    {% include 'TwigBundle:Exception:logs.html.twig' with { 'logs': logger.logs } only %}
</div>
```

Some hints are welcome.

There are no easy way to slice nodes in specific range. I created a method using \LimitIterator. Works fine for me.

An example using is:
```php
     $crawler->filter('h1')->slice(5, 10)->each(function ($node, $i) {
         return $node->text();
     });

This new command allows to set ACL directly from the command line. This useful to quickly set up an environment and for debugging / maintenance purpose.

This PR also includes a functional test system for the ACL component. As an example, it is used to test the `acl:set` command.
The provided entity class is not mandatory (tests will still be green without it) but can be useful to test other ACL related things. I can remove it if necessary.

The instantiation of the `MaskBuilder` object is done in a separate method to be easily overridable to use a custom one (e.g. the SonataAdmin one).

[Yaml] Added support for object maps

Previously, the parser treated maps ( {} ) the same as sets ( [] ).
Both were returned as PHP associative arrays. Since
these are distinct entities, this can cause considerably problems for
the users, especially when YAML is being serialized into another
format such as JSON.

This commit allows the user to enable object-map support via a third
parameter on the Parse method.  It defaults to `false`, which means
that this commit does not break backwards compatibility.

If the user enables object-map support, maps are represented
by stdClass() objects.  Sets remain as arrays.
