Support object initialisation shortcut {a} == {a:a} from ES2015
Object declaration in Twig is very close to the Javascript syntax and is targeting the same profil of developers. In order to provide a smooth developer experience, Twig should implement some new feature of ECMAScript.
Since ECMAScript 2015, a short syntax can be used to declare an object when the key is identical to a defined variable (see [MDN doc](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Object_initializer))
```js
// Shorthand property names (ES2015)
let a = 'foo', b = 42, c = {};
let o = {a, b, c}
```
This PR adds the same syntax to Twig.
This can be very useful for `include ... with ... only` :
```twig
{% set title = "My title" %}
{% set image = "image.jpg" %}
{{ include "template.twig" with {title, image} only }}
# instead of
{{ include "template.twig" with {title: title, image: image} only }}
```

Twig, the flexible, fast, and secure template language for PHP
==============================================================
Twig is a template language for PHP, released under the new BSD license (code
and documentation).
Twig uses a syntax similar to the Django and Jinja template languages which
inspired the Twig runtime environment.
