Implement FilePropertiesDialog

Implemented a dialog for file properties. When the mime type says it's a
video, fork ffprobe to read the properties of all streams and show them
in a QTreeView powered by a SmTreeModel. If the mime type is image, use
QImage to read some properties and show them in the same dialog.

This commit introduces the new class FilePropertiesDialog. I also had to
implement a copy constructor for SmTreeItem. It obsoletes classes
ActorWidget, ActorModel and MoviePropertiesDialog.
