Richard van der Hoff 6396c60645 Put a cachebuster in the names of CSS and JS files
This means that clients can do better caching of assets, as it will mean we are
no longer reliant on etags to ensure that clients get a fresh version.

We inhibit the cachebuster for `npm start`, so that we don't get millions of
copies of the bundles on dev boxes.
