[Xmonad] darcs patch: make quickcheck tests friendlier to read.

[David Roundy]

Hi all,

This is just a silly patch to make it easier to deal with failed quickcheck
properties in ghci.  Derives a read instance for StackSet, and makes
windows T be Char, so they're easier to distinguish when a StackSet is
printed.
