[xmonad] darcs patch: broadcastMessage now uses Operations.windows to update...

hi, this is a follow up of my previous "broadcastMessage should not call modify". This is a proposal of the new approach, in order to show that it fixes the issue #111. Cheers, Andrea (ps: sorry for the noise, but I think this is urgent, as issue #142 shows.) Thu Feb 21 15:18:50 CET 2008 Andrea Rossato * broadcastMessage now uses Operations.windows to update the windowset This is a fix for issue #111: - broadcastMessage and restart moved to Operations; - added sendMessageToVisible and sendMessageToHidden - broadcastMessage will use sendMessage* functions now. TODO: remove Core.runOnWorkspaces and refactor sendMessageToWorkspaces accordingly.
