* Add a TreeViewer that constructs a DynamicTreeViewer whose UI provider
  uses the methods and kernel services for IHierarchicElements and
  NamedElements.
* The Viewer uses a composition principle where a client must provide
  TreeView (JavaFX), a root element (AF3), and a content provider that
  selects the elements to be displayed.
* Add two basic content providers that a) list all children below the
  given root element and b) list all children of a given type.

* Since the tooling helpers used in the svn installation and the git
  version, a re-rating of all files was required (less work than fixing
  the tooling code that would be only used once).
* Updates the hashes of the classes in the .rating files.
* Removes empty .rating files from directories without ratable files.
