Initial implementation of the bulk ban check system. This implementation takes a snapshot of the currently connected clients, sends it up to the master server, and the master server returns anything within this list that is marked 'banned'. The server would then kick the player from the server. This commit also removes the global banned list cache, as the bulk checking system offers a lot more freedom regarding banning specific players and have it sync across all available servers.
