[xmonad] darcs patch: fix documentation to match implementation (and 2 more)

Fri Nov 13 21:13:28 EST 2009 daniel@wagner-home.com * fix documentation to match implementation Fri Nov 13 21:36:16 EST 2009 daniel@wagner-home.com * generalize IO actions to MonadIO m => m actions This should not cause any working configs to stop working, because IO is an instance of MonadIO, and because complete configs will pin down the type of the call to IO. Note that XMonad.Config.Arossato is not a complete config, and so it needed some tweaks; with a main function, this should not be a problem.
