[Xmonad] darcs patch: move event loop out of mouseDrag.

Hi all, Here's my patch to do dragging in the X monad. (It's here a couple of weeks early because my wife brought the laptop into my office today to check email.) It's pretty simple. I don't yet have a decent use for it, but a patch to XMonadContrib which fixes things to compile with this change will follow.
