This adds in an additional log message pointing folks to https://goo.gl/SC7cgQ (I could use a different URL shortener or just include the full URL if you'd prefer.)
It's displayed every time registerServiceWorker() is called and there's a service worker active on localhost. Displaying it on each load should give it higher visibility vs. the other logging messages which are only displayed when content is initially cached or content is updated.
I hope it will help with the type of questions that come up at, e.g., https://github.com/facebookincubator/create-react-app/issues/2398#issuecomment-344510011
