[racket] Gambit Scheme for the iPhone and iPad

I stopped reading comp.lang.scheme some time ago, so I wasn't aware 
until just now that in early May, Marc Feeley succeeded in placing a 
Gambit Scheme universal app (iPhone/iPad) in the App Store.

This is the first indication I had that Apple had relaxed their App 
Store restrictions sufficiently to permit real programming language 
interpreters. I thought others on this list might be interested in 
knowing this fact. --PR
