Reorganization and cleanups of Unit Tests

* Reorganized tests to accommodate split into Logic & Application.
* Eliminated 'Spec' naming in favor of 'Test' as the suite is entirely based on SenTest.
* Pulled majority of testing support classes up into the library and documented them.
* Introduced RKApplicationTests app for running the RKTableController UI tests
