Move CSS to Webpack

Using both the asset pipeline and webpack is confusing
and leads to unpredictable results in production.

This commit moves all (S)CSS to Webpack under `app/javascript/scss`
so that we can test whether the development interface results
in a consistent production deployment.

In order to load the ForkAwesome fonts we used a long path:
`$fa-font-path: "../../../node_modules/fork-awesome/fonts";`
Not sure whether this works...
