Use Helthe Turbolinks Component

Thanks for taking the time of making a Turbolinks package for Laravel! The goal of the [component](https://github.com/helthe/Turbolinks) was to offer a baseline package for other projects using HttpKernel or HttpFoundation (like Laravel) to integrate turbolinks.

I made some changes so that you don't have to use your own javascripts or middlewares since I made one for [Stack](http://stackphp.com/).
