Rescreen is in main xmonad now

--- Grabs new screen information.  Useful for randr setups.
--- To use rescreen, add a keybinding in Config.hs. For example:
--- , ((modMask .|. shiftMask, xK_F12   ), rescreen)

--- TODO Get this code into xmonad when it is ready for randr support.
--- Make it happen automatically on randr events.  It's currently 20 loc, but I
--- believe it can be shrunk a bit.
