Sybren A. Stüvel 76a24243f0 Manager: Introduce event bus system
Introduce an "event bus"-like system. It's more like a fan-out
broadcaster for certain events. Instead of directly sending events to
SocketIO, they are now sent to the broker, which in turn sends it to any
registered "forwarder". Currently there is ony one forwarder, for
SocketIO.

This opens the door for a proper MQTT client that sends the same events
to an MQTT server.
