-Once in a while .... (set_event_filter) +SDLpp.pl: Packaging SDL Scripts Alpha

-So I have been hacking for a while on SDL::Events::set_event_filter. The code below is an example usage. The magic behind this is here
+Here is the shooter.pl packaged up:
+
+
+We are looking into testing this on a Mac Build server.
