Handle Websockets Closing

[vkoves]

Websockets close after a timeout, and this can cause the UI to no longer work and respond. This should be handled either via:

• Informing the websocket disconnected and asking them to refresh
• Trying to reconnect the websocket on an action being taken

Here's a screenshot of this occuring with me trying to join a lobby after leaving a tab in the background for a few minutes:

Since the UI doesn't handle this error, to a normal user you would just be confused why pressing Join Lobby isn't doing anything.
