Subject: Up to now DolphinView and ColumnWidget contained a lot of code
 duplication regarding generating previews and the dimming of cut items. This
 has been refactored by introducing an IconManager which takes care itself
 about generating a preview and dimming cut items. This also allows improving
 the speed of previews in (near) future (at the moment showing previews from
 the cache is a lot slower than in KDE 3...).
