Human client timeout error message incorrect

[JacobFischer]

When playing as a human client, if run out of time a fatal message is sent from the server.

The error message currently is confusing due to a lack of a string.format call. However fixing this causes the error to disappear after about a second, which is less useful.

In addition, when a game ends (or you timeout). the ticker should stop ticking. It might be good to update the player pane that they timedout as well.
