Provide a WebSocket for Events

[dns2utf8]

Let a Client connect to the Server with a WebSocket, so the Server can send Events to the Client without the Client polling it.

What do you think?

That would be interesting indeed :)

After another though, we could also use Server-Sent Events to send events to clients over HTTP. It's probably simpler to implement and use.

Looks hard to implement at the moment: https://stackoverflow.com/questions/38179117/how-can-i-use-server-sent-events-in-iron

Furthermore, since Iron is synchronous, we'd probably keep an entire Thread busy with sending out events.

In the long term, we should probably move to an async solution. Maybe with actix-web?
