Rubygame

I ended up having to do some not-so-minor changes to Clock today (to satisfy my OCD rigorous Quality Assurance procedures), so I didn't quite have enough time to prep the Rubygame 2.5 release tonight. The code is done (pending further review in the morning), it's just a matter of packaging it up and posting to various sites and mailing lists. I'll take care of that in the morning.
