Add New Items Finder progress information for ProgressManager.
Original code for Marcel use StatusProgressBar indicator. We can do better with ProgressManager now.
The goal is to remove definitivly StatusProgressBar from AlbumGUI.
Code to manage StatusProgressBar event from icon view still active for actions Captions & Tags. Still TODO.
NOTE : The progress indication in percents from ScanControler sound like completly crazy and not suitable as well. Why ?
