[xmonad] darcs patch: New Layout X.L.MultiColumns (and 1 more)

Sat Oct 24 19:51:55 CEST 2009 Anders Engstrom * New Layout X.L.MultiColumns New layout inspired the realization that I was switching between Mirror Tall and Mirror ThreeCol depending on how many windows there were on the workspace. This layout will make those changes automatically.
