New look for KOrganizer

Tim Jansen has committed the new look for KOrganizer's agenda view (Screenshot). This is a big improvement. People were complaining from time to time about the "boring" look of KOrganizer. Now they don't have a reason for that anymore (Well, I'm sure somebody will come up with another reason to complain ;-).

Now I just have to unbreak libkcal. Seems like my 200k patch from yesterday broke recurring events...
