Use webpack to create a module as output

[nrc]

We currently just use webpack to translate JSX in the JS files, then a script (cp_static.sh) to copy files around (plus some handlebars stuff - build_templates.sh). We should do all this build system stuff in one place - using webpack.

Since you are using React now, do you also plan to replace the remaning handlebar templates into React components?

Yes, I do
