Remove from queues after website inactivity. #120
Description
We should add a timer which logs people out if their websocket has not been connected for a very long time. Set a backend timer which gets set on websocket close to run an hour later? on websocket connect, check if there is a timer for that user and remove it. If the timer goes off, remove the user from their queues. I think we are safe to leave them having their devices since those will time out naturally.
