External dependencies

Can't use Thingspeak as it is on the repository deployed inside an internal network because it's trying to fetch static resources from external CDN's.

In addition to these resources above, there's also a dependency on the licensed Highcharts JS (eg https://github.com/iobridge/thingspeak/blob/master/app/views/charts/show.html.erb) in several locations in the code used to display charts. The resources are hosted on thingspeak.com which is one thing, but also I'm curious as to whether it's a potential licence violation for me to be cloning this repo and reusing Highcharts (even if on that hosted location).
