3369 fix missing ids no command

See merge request !2

* Add style sheets for a native look of JavaFX-based views such that the
  UI does not break too much in comparison to the SWT-based views.
* Windows 8/10, Windows 7, and MacOS X are supported. For Linux (GTK/QT)
  no style sheets have been found at the creation time of this commit.
* The style sheets for the Windows 7 and the MacOS look are bundled in
  jars that define additional controls for animation etc. These libs
  are not usable with the SWT/JavaFX integration layer since it is
  impossible to load the control classes defined in the CSS file. The
  reason for this resides in the special classloader architecture of the
  JavaFX/SWT integration where it is impossible to inject classes into
  the classloader hierarchy without modifying e(fx)clipse plugins, or
  writing custom classloader/wrapper plugins for osgi.
* The licenses of the imported CSS files are 2- and 3-clause BSD
  licenses which are placed in the folders containing the CSS files.

* Move the existing apache commons jars to a subfolder in the lib
  directory.
* Add the license file in the apache commons folder and include it in
  the build variants.
* Add the apache commons lang3 library that can be used in parallel to
  the older lang library due to different namespaces. It will be applied
  for differentiating between recent OSes, for instance.

- 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.
