Lobbies and stuck players

A player kicked from their server has no server until they join another one. RoodyProxy tries each lobby once; if none works, or limbo-maximo-segundos pass without a server, it disconnects them. So a client that no longer answers does not keep bouncing between lobbies for minutes or hours holding its name.

If someone joins with a name that is already online, the old session is closed when it comes from the same IP or has been without a server for a while. Otherwise the new one is refused.
