update nightscout web monitor

Howdy,

This is a pull request to update your version of the `cgm-remote-monitor` to our _experimental_ version.
This version includes `<yoursite>.azurewebsites.net/clock.html`, which only displays the last cgm reading, extra large.  There are a number of other things that have been updated, I'm happy to answer any questions about it.

Follow the link to the pull request, and use the green merge button to confirm the update.  Shortly after, you should be able to observe a new deployment, and your website should update automatically within 5 minutes.
