Webpack build for dist

[roblarsen]

This will close #2650

Testing dev

git fetch 
git switch 2650-create-webpack-build-to-ship-with-the-project
npm install
npm run build
cd dist
npm install
npm run start

The webpack served files should now run, in a browser. Edit and the site should update automatically.

Testing the build is the same, set-up with the build command replacing start

npm run build

There should be a new dist folder with a Webpack optimized build. I test this folder using serve

This does what I expect it to do (except for that merge conflict)

And the failing build 😩
