[racket] Congratulations to Shriram: Milner Young Researcher Award

Shriram Krishnamurthi has been selected as the 2012 winner of the
SIGPLAN Robin Milner Young Researcher Award!

The Milner Award is new this year, but with this year's precedent, it
will surely prove to be the most prestigious SIGPLAN award that is
possible for a researcher within their first 20 years. The award was
announced minutes ago here at PLDI, and the award citation will soon
appear at the following URL:
