Title: Own our fiddles so we can update them more easily

The fiddles in Thinking in React were using 0.5. That would have been fine on it's own but then #2491 came along and just updated the API usage without updating the version. And then the base fiddle were @vjeux's. This brings them all under one roof and then we can share responsibility for updating.
