Tree-wide: Update ratings to mirror the rating state of the svn repo.
* 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.
