[xmonad] darcs patch: Expanded on X.L.Maximize functionality (and 1 more)

Sun May 3 02:10:52 CEST 2009 Jan Vornberger * Expanded on X.L.Maximize functionality 1. Move maximized window into the background when it's not focused. 2. Changed semantics so that maximizing a different window will automatically restore the currently maximized window and maximize the new one (previously this had to be done in two seperate steps). Sun May 17 01:35:57 CEST 2009 Jan Vornberger * Replaced more stuff in X.L.Maximize with pure versions
