Urban Dictionary - follow the style of the Dictionary IA (WIP)

Fix for issue #704 - work in progress. It misses the audio part, which I suppose needs to be done redirecting to the Wordnik's API, but how? Do you have any particular function to redirect requests to other Spice APIs? I've first tried to accomplish this result by myself, but...

Anyways, first screenshot, Desktop view:

Nice! I think I would like it better if it was split in the normalize function

```javascript
{
    example: item.example.split(/\r?\n/)
}
```

And then we build the HTML in the Handlebars template

```handlebars
{{each example}}
    <div class="example">{{this}}</div>
{{/each}}
```

I'd like to prevent concatenating HTML as much as possible because:

- HandlebarsJS will escape each item for us.
- It's not very readable.
