Loopback - Bug Fix

There was a minor bug in the in game menu interactions that allowed you to get to wave 10/9. Clearly this is beyond the scope of the theme and I have fixed it. I also added some functionality to dump replays to a file and load them again later which might have some debugging potential. That is the extent the changes I have made. Judging should naturally be based on version 1.0 which we submitted earlier, 10/9 bug included. :-)
