[xmonad] Mouse focus without entering window

[Daniel Wagner]

Well, I haven't tested it, but the code of `takeTopFocus` looks pretty
different to me:

    withWindowSet $ maybe (setFocusX =<< asks theRoot) takeFocusX . W.peek

To me, that reads as "if nothing is focused, focus the root window",
whereas the desired behavior is "no matter what's focused right now, focus
the window under the mouse". So both the condition and the action to take
seem different to me...?
