RatingService Phase 1.

The RatingService will allow users to apply ratings to content nodes in the repository.
  There will be a number of built-in Rating Schemes and support to add more by the usual extension mechanism.
  Out of the box, we envision a 'likes' scheme (user X likes this document) and a 'star' rating
    (user X gave this document 3 out of 5 stars).

  Content model for ratings.
  Spring config includes two out-of-the-box rating schemes
  Various basic infrastructure classes for Ratings, RatingSchemes and the service itself.
  Basic CRUD for ratings in a Java foundation layer.
  Associated JUnit tests.

The next contribution will add support for per-node average and total ratings and associated tests.
