javascript_include failure

In app/views/index.volt there will be javascript included, but the sourcefolders aren't right:

```
    {{ javascript_include("js/jquery.min.js") }}
    {{ javascript_include("js/bootstrap.min.js") }}
```

should be:

```
    {{ javascript_include("js/jquery/jquery.min.js") }}
    {{ javascript_include("js/bootstrap/bootstrap.min.js") }}
```

Then the nav-collapse wil work in the browser :)
