Dev command
Adds a dev command for the webpack client js stuff.
The idea for now is that you run it outside the docker-compose environment by running:
cd client
yarn dev
And then visit localhost:8080.
It'll serve up the webpack files directly, do some hot reloading/refresh, and proxy the other requests to localhost:18080 to be served by the docker-compose environment.
I didn't document it yet, as would like to see how it works out in the short term.
