getGameConnectionHandler

Gets the game connection handlers that are invoked whenever the client logs in or reconnects. These functions are only triggered after features such as Proof of Work and remaining beta archive CRCs have been obtained, furthermore additional library-sided checks, such as not too many connections from the same INetAddress must be met. Session id is also verified by the library before passing the request on to the implementing server. The server is responsible for doing all the login validation at this point, as well as CRC validations. It is worth noting that the connection handler will be invoked from whichever thread was used to decode the login block itself. By default, this will be one of the threads in the ForkJoinPool.
