Title: Add response contains json property

When working with randomly inserted data within API tests you might not know when you assert an response like:

```
{
"name": "john"
}
```

what the name actually is. So you can not only work with ``seeResponseContainsJson(array('name' => 'john'))`. This patch applies a function with which you can check whether a specific property exists in the response's JSON object.
