DATAJPA-329 - Prepare next development iteration.
DATAJPA-331 - Use correct snapshot repository to resolve plugin dependencies.
DATAJPA-332 - Optimization for SimpleJpaRepository.findAll(…) taking Iterable.

We now shortcut the execution of SimpleJpaRepository.findAll(Iterable<Integer> ids) to return an empty collection in case no ids or null are given. Previously building a query with an IN clause failed with an empty parameter list given.
DATAJPA-323 - Added integration tests for JavaConfig and Repositories.
DATAJPA-334 - Fixed referenced JUnit runner in readme.md.

SpringJUnit4TestRunner -> SpringJunit4ClassRunner.
DATAJPA-338 - Prepare 1.3.2 release.

Updated changelog, polished pom.xml for release.
