Unify ready and reconnecting properties into a single status property
and future-proof Message class
The state of the WebSocketManager is now represented by a single
status property, removing emittedReady
and reconnecting as representations of state.
Message class will now also cache users it isn't aware of that appear
in mentions and authors.
