Play Framework

Changed the logic to explicitly save JPASupport to explicitly save JPABase.  I'm doing this because in the Scala module we have a problem where properties on models are implicitly saved when they are changed.  There is a longer account here: http://github.com/guillaumebort/play-scala/issues#issue/14

There does not appear to be any issues with making this change.  All tests that were passing are still passing.
