logic: Directory list box now restricts the user to select files, directories or both if required

* split QtDirectoryListBox and QtStringListBox * renamed QtDirectoryListBox to QtPathListBox * extracted QtListItemWidget class to own file * renamed QtListItemWidget to QtListBoxItem * added SelectionPolicyType to QtPathListBox to allow for specifying if selecting files, directories or both should be allowed.
