CDN twemoji not working

[jguidini]

Hi!

I'm using demo page, and this days the result of markdown (right box) shows nothing.

Inspecting I'ved found an 404 error, see:

After some googling found the root cause: https://github.com/twitter/twemoji#cdn-support

MaxCDN has shutted down.

To solve this, on index.html change the old CDN by the new one:

 15     <!-- <script src="https://twemoji.maxcdn.com/twemoji.min.js"></script> -->
 16     <script src="https://unpkg.com/twemoji@latest/dist/twemoji.min.js" crossorigin="anonymous"></script>

I would be grateful if update the code of demo page.

Thanks.
