Upgrade to Webpack 2

[optikfluffel]

We should probably migrate to webpack 2 and update all other dependencies along the way too. I could give it a shot during the following week if that's ok with everyone. Any thoughts on that?

Porting the loader is the tricky part - this repo is mainly just boilerplate around that. A PR has already been made for the changes for webpack v2 on the loader, elm-community/elm-webpack-loader#105

I would love some help reviewing stuff there, if you already familiar with that migration.

@optikfluffel Please review my PR #53 and let me know if you find any issues.

Sorry @optikfluffel, forgot to watch this repo, so didn't see your review. I updated code based on your feedback. Thanks a lot!.

BTW, I create a new starter project at https://github.com/jiwhiz/elm-bootstrap-webpack-starter, with elm-bootstrap support, and made elm-css-webpack-loader working. Hope you guys give me some feedback. Not a frontend developer, but love Elm so much!

Just rooting around this repo and noticed the changes that have been made recently. With 4a2d21c done, can this be closed?
