[cr] Integrated: index.html: inline js

[Erik Helin]

Hi all,

please review this patch that inlines `webrev.js` into `index.html` to avoid an additional network request. It would have been better to keep the JS in a separate file if we could:

- minify the JS
- configure cache control headers

GitHub Pages unfortunately does not allow any of the above (and we don't want a build step for minification), therefore the best option is to inline the JS into `index.html`.

Thanks,
Erik
