Include webpack for assets bundling
This MR removes the bulma css files and replaces them with imported bulma sass files. This makes it possible to customize the generated css: https://bulma.io/documentation/customize/concepts/
I also included bundling for TypeScript if that's interesting (i highly recommend it).
What we need to figure out in the future is how to handle cache busting when updating the assets when the app is live.
