Connect live data flows

[loleg]

Since dribdat has it's origins in the IoT community and we are planning some fresh events next year, I thought it would be good to collect some new ideas for embedding live data / sensor-based projects in the app.

ThingSpeak, for example, has an embed code which could be easily used to showcase a chart or whole dashboard.

Node Red, which has a helpful Embedding into an existing app page with some JavaScript code.

Other examples and suggestions welcome. See also #313 for rendering ideas, #100 and #115 for prior discussion.

The v0.6.7 release makes some minor improvements to the dashboard, but overall this area is still wanting.

I had considered creating a new live data feed with https://github.com/keen/dashboards

Now we have a separate project underway in the Moodboard channel.
