[xmonad] XMonad.Actions.CycleWS export screenBy suggestion

[Joachim Breitner]

Dear Linus,

it might have been that I started the CycleWS module (I don’t even
remember :-)) but since then, it was mostly developed and extended by
other members of the community. I’m therefore replying to the xmonad
mailing list with full quote, hoping someone there can pick up your
suggestions.

You can also file a bug report so that this is not forgotten.

Greetings,
Joachim
