- Added two new classes to handle cover download
Simplified DownloadItem constructor

messages notifier and hide controls when no song is playable
Removed outline from play/stop buttons
new member storing covers cache path
Replaced model/view for search results with a generic QListWidget; without
increasing memory footprint I can succeed creating more complex items, and
shadows consistency. model/view source code is kept in place.

Show refresh button when file already downloaded
Fixed file naming issue
Using QSharedPointer to manage a Song
