Use ES6 modules, use module bundler

[simon04]

• install packages from npm via
• use ES6 module export/import
• use webpack for bundling the application
• make the tests run again

This is work in progress; so far items 1+2 are started but not yet finished. What do you think?

What do you think?

Definitively a +1 from me. Thanks for tackling this!

Maybe we can also add to the todo list:

• get rid of duplication between index.html and index_packaged.html (same for map*.html)
• switch to different publishing mechanism: use gh-pages branch to contain only bundled stuff (like this maybe)

You can give it a try: npm install && npm run start for a development server and npm run build for a minified distribution build (see README for details).

I think we can drop the _packaged.html files completely. It's now just a matter of running webpack in a different mode.

I still have to look into building map.html. Eventually, we can get rid of quite a few files in the repo.

Yes. That's what I meant. ;-)

I've pushed this PR onto a new branch in this repo now and added you as a collaborator, so we can work on this together! I'm opening a new PR for that branch in a minute.
