+ Merver sends player ids along with locations
+ This means a newly logged in client will need to know which id is
+ assigned to it
+ So server needs to send an id message, wait for an ack, and then send
+ the location messages
+ When a client shuts down, it sends a message to indicate this so the
+ server can remove it from the list of connected clients
+ Eventually, there'll need to be a way to detect timeouts from clients
+ (if they crashed or otherwise failed to send the logout message)
