Change the NetServer Broadcast function to send the given message to clients that are in one of the states specified by the caller.
Thus remove the peculiarity to broadcast to clients that are in the gamesetup, loading screen or ingame, but not rejoining ones.
Fix "unknown player" errors in the GUI by broadcasting player assignments to rejoining players too. Fixes #4036.
