Instead of translating between the sorting proxy and the underlying file system model at all the DirectoryView API boundaries, just hand out indexes into the sorting proxy model. The only thing those indexes are used for on the outside is to retrieve a GUI::FileSystemModel::Node for an index, so add a nice helper on DirectoryView that turns a ModelIndex into a Node&.
