Changed Serializer/Deserializer API in preparation for event recording.
Pressing 'Ctrl e' now starts/stops event recording (key is temporary and will probably change). An state file is then generated containing the state when recording started, and the eventstream up to the point when recording stopped. Next I'll work on loading the event state file and replaying the events. This one is a little harder, since it has to override EventHandler::poll() and use events from the eventstream. Hopefully rudimentary support will be there by the end of the weekend. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@906 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
