Typeable has been automatically derived for every type since GHC 7.10, so remove these obsolete derivations. This also allows us to get rid of the `DeriveDataTypeable` pragma quite naturally.

-- $usage
|
|
-- Allows you to dynamically declare windows as scratchpads. You can bind a key
|
|
-- to make a window start/stop being a scratchpad, and another key to
|
|
-- spawn/hide that scratchpad.
|
|
--
|
|
-- Like with XMonad.Util.NamedScratchpad, you have to have a workspace called
|
|
-- NSP, where hidden scratchpads will be moved to.
|
|
--
|
|
-- You can declare dynamic scrachpads in your xmonad.hs like so:
