Forgot to add the pong.js

Working through the pong as this goes on, has been taking longer than I
was expecting, as usual. Finishing it by tonight is looking less likely,
but it's going to have to get done if I want to add remote MP tomorrow.

They said they're looking for code elegance and creativity, but I'm not
sure how much of that I can deliver in two days! Still though, it's nice
to have a short deadline like this, really fun to see how far I can go in
such a short amount of time.

Actually, they can't expect a online MP in two days, at least not very
well done, just because thinking back, how many games have had MP
implemented during the 48 hour Ludum Dare... Still though, I'll try for
about half a day, and then just focus on making what I've got look good.
