* hide the implementation type in "EwmhDesktopsLayout"
Instead of exporting the EwmhDesktopsHook type, which is used internally,
export a type alias for (HandleEvent EwmhDesktopsHook), so users don't have
to update their xmonad.hs if the implementation changes.
It could also be wrapped in a newtype, instead of a "type", but that would
require manual instances of the various classes, as ghc can automatically
derive the LayoutClass instance.
