Fixed pong src checked in

[Bill E]

Back a ways, it was determined that the source for pong that's in the main distro in tapes/source didn't actually work. It also differed from the rim of same. The problem was an ioh after dpy. I finally checked in the (verified working) fixed version, but only in my repo as a separate file, FunStuff/Pong/pong.am1. Yes, it's am1, but the fix can be applied to the original source easily, just delete the several ioh instructions and that one will also work.
