- UniqueIdUtils:
    - Remove fixMissingIDs(final ITopLevelElement modelElement)
      (only used in one place)
    - fixMissingIDs(EObject object, EObject existingModel): Do not wrap
      model modification into a command. This is up to the caller of
      this method (e.g., the command stack is not available in tests) 
- Remove IDMigrationProvider: Fixup of missing / duplicated is handled
  in ModelContext
- ModelContext: Use nonDirtyingCommand, and automatically save model
  in case IDs have been fixed

* 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.
