  * Service Worker generator now generates relative URLs for pre-cached assets instead of absolute. This makes it possible to cache assets when the app is served from a non-root path without re-mapping all URLs. Since server workers fetch relative to their own URL, there is no effective change for service workers served from the root path.
  * Service Worker generator now better caches the entrypoint by setting navigateFallback and related options.
