ProjectExplorer: improve treescanner scan result

Allow returning all folders scanned by the treescanner. This will be
used in the WorkspaceProject to also show empty folders in the project
tree. Additionally we are now able to iterate over the complete tree of
folder nodes and add the paths to the watcher instead of walking the
directory tree again to collect all directories to watch.
