Realtime #44

How complicated would it be to add realtime support?

It would be great if we could subscribe to new measurements (for all sensors), for example over a WebSocket. (SSE would be another option, but it's far less well supported than WebSockets.)

Cool idea. Should be easy with ActionCable.

Ok, let's do some speccing:

Application fetches initial state (sensors + historic data)
Application subscribes to a WebSocket endpoint
Every time a new measurement arrives, that data is pushed as a "measurement" event to all subscribers
The subscribers receive the update and add it to the currently displayed data.
