[Xmonad] darcs patch: new module NoBorders to let a given layout have window...

Amended due to stupid mistakes... Sun Jun 10 14:41:28 PDT 2007 David Roundy * new module NoBorders to let a given layout have windows without borders. This is designed for layouts like full and tabbed, where the red square around the screen actually conveys no information (except for weird windows that use the shape extension or something, so that more than one window is actually visible). Save some real estate at no cost.
