[xmonad] Ignore single window for focus follows mouse?

[Joseph Garvin]

I'm close, but I only know how to get the opposite of the functionality I
want. The code below prevents focus on all windows except those with the
name "Call with " but I actually want it to focus on any window except that
one. But ManageHook doesn't define a negation operator, just "=?", so I'm
not sure how to do it (pardon my lack of haskell literacy ;p). Also, what I
really want to do is match the regex ".*Call with.*" but I figured I'd try
to get it working with an exact name first.

In general, when you have a Query Bool, is there a way to get the Bool out
of it so you can do normal operations? I know this is related to how monads
work, but I don't really understand xmonad's architecture yet.

-- Focus follows mouse is annoying for skype
followEventHook event = followOnlyIf (notSkype) event
  where notSkype =
          runQuery ((stringProperty "WM_NAME") =? "Call with ") (ev_window
event)
