[Haskell] New TMR editor

[Wouter Swierstra]

Dear all,

After several years at the helm, I've decided to step down as editor  
of the Monad.Reader.

I am happy to announce that Brent Yorgey will take over my role as  
editor. I'd like to take this opportunity to thank Brent for helping  
to keep the Monad.Reader alive. I'm sure he'll do a fantastic job.

Finally, I'd like to thank all the people who have contributed to the  
Monad.Reader over the last few years – you guys have made this  
publication, and my job as an editor, so much fun.

All the best,

   Wouter
