Filter to match colours to selected palette and optionally apply some simple dithering.
Fixed copyright notice.
Removed alpha component from rtree search.

Added palette specialisation to KoResourceItemDelegate::paint so palette thumbnails wouldn't be tiled when palette image smaller than thumbnail size.
