The hapi-fhir-jpaserver-example project's JpaServerDemo supports DSTU1 and DSTU2, but not DSTU2.1

Not a big deal, but would be nice.

I've created Pull Request #279 to address the JpaServerDemo changes needed. In addition, the following patch can be applied manually to address the other files that need to be updated to switch things to DSTU2.1:
