[xmonad] darcs patch: New module XMonad.Actions.GroupNavigation

Fri May 7 15:32:26 CEST 2010 Norbert Zeh * New module XMonad.Actions.GroupNavigation This module allows the navigation of windows by groups, where a group is defined as the set of all windows satisfying a specified boolean query. The first set of functions simply allows the cyclic forward/backward traversal of the list of windows in a group, possibly performing a custom action if the group is empty. The second set of functions adds a facility to keep track of the focus history of all windows and uses this history to allow jumping to the most recent window in a given group.
