Make KListView capable of drawing categories on our own way. This make things easier

when we are trying to customize it. We can also benefit from KStyle if some day it 
supports category drawing.

KListView keyboard navigation. Tricier than I thought.

Pending renaming to KCategorizedView. Seems a good name.
