maybe use azure deployment script?

Howdy, these changes add some scripts that azure runs when deploying the project.
The idea was to allow azure to automatically deploy, run `bower install`, and anything else needed when `master` branch changes on github.

Assuming this method works, the web gui for managing azure deploys allows rolling back to any previous version deployed this way.  I added a skeleton azure deploy script generated using the `azure-cli` node package, and then removed most of the `KUDU` stuff which seemed broken.

The result seems to deploy all the assets, and allows fetching data via `/pebble`.
On Azure, the [cgm display appears blank](http://nightscoutba.azurewebsites.net/), with no data, while [my setup with these changes produces very nice results](http://bewest.io:8080/).
