Major test-case cleanup.

- Removed JMock dependency, tests rewritten to use Mockito for stub/mock
- All test should now be using JUnit annotation-style tests
- All modules should now depend on same JUnit version
- Rewrote a few tests to better utilize JUnit annotations
- Fixed a few broken tests
- Code style changes
