* server/WorldRouter.cpp: Slightly randomize starting position of characters to avoid getting stuck. * rulesets/mason/define_world.py: Move the world contents around a bit to make room for larger spawn area. * rulesets/World.cpp: Make sure we don't degfault if we get a height outside current area of terrain. * client/ClientConnection.cpp, client/CharacterClient.cpp: Set an error condition if the server disconnects unexpectedly, and thus return an error to the script causing an exit.
