Upgrade to Hibernate 5.2.1 and Spring Framework 4.3 to pull in the necessary tweaks to let the latter work with the former.
Excluded hibernate-entitymanager and refer to hibernate-core instead as the 5.2 release has merged the artifacts and the former is not available anymore.
The project showing the stored procedure support still needs to stay on Hibernate 5.0.7 because the stored procedure support on HSQLDB has been broken since 5.0.8. The original issue [0] has been fixed but running the module on 5.2.1 now runs into a NullPointerException from AbstractProducedQuery [1].

Requires an upgrade to snapshots as the JPA implementation is broken in Hopper SR1 but will be fixed in SR2 (Boot 1.4 RC1). Switched to use @SpringBootTest in test cases.
Upgraded to Spring Boot 1.4 M2 and thus Hibernate 5.1 transitively.
Switched to H2 as database for all examples using JPA by accident as the
invalid error logging for HSQLDB schema creation got worse in 5.1 (see
[0]). The JPA examples themselves have to stay on HSQLDB as H2 doesn't
support stored procedures. The stored procedures example in turn has to
be downgraded to 5.0.7 as all following versions currently break stored
procedure execution support [1]. Reworked the JPA auditing example as
5.1 breaks on generic types used in support types like AbstractAuditable
[2].
Tweaked content type assertions in some REST related test cases as
Spring 4.3 returns an encoding alongside the media type.

Got rid of Guava dependency in favor of JDK 8's Optional. Upgraded basic JPA example to Spring Data Hopper to get access to the newly introduced functionality.
Removed obsolete @Param annotations from repository interfaces. Upgraded to Fowler snapshots for JPA 2.1 examples as we need a fix in derived stored procedure execution to work correctly.
Related issues: DATAJPA-681.
Abbreviated JPA sample module folder names. Renamed the Java 8 auditing sample module to Java 8 module as it not only contains samples for auditing anymore.
