getINetAddressHandlers

Gets the handlers for anything related to INetAddresses. The default implementation will keep track of the number of concurrent game connections and JS5 connections separately. There is furthermore a validation implementation that will by default reject any connection to either service if there are 10 concurrent connections to that service from the same address already. The initial check is performed after the login connection, when either the game login or the JS5 connection is established. For game logins a secondary validation is performed right before the login block is passed onto the server to handle. It should be noted that the tracking mechanism is fairly straightforward and doesn't cost much in performance.
