 Abstract:
 This class is the base Game controller in RealtimeMultiplayerGame on the server side.
 It provides things such as dropping players, and contains a ServerNetChannel
 Basic Usage:
 [This class is not instantiated! - below is an example of using this class by extending it]

 (function(){
		MyGameClass = function() {
			return this;
 		}

		RealtimeMultiplayerGame.extend(MyGameClass, RealtimeMultiplayerGame.AbstractServerGame, null);
