[webkit-dev] Darin Adler is a machine

[Eric Seidel]

At request of folks in #webkit I ended up making the script nicer...
now that I have it all fancy, I've posted it on a bug:
https://bugs.webkit.org/show_bug.cgi?id=26533

Maybe it can be stripped for parts some day...  Or maybe we should use
it to clean up the ChangeLogs to actually have nice names for all
reviewers. :)

Either way, back to real work...
