Related to PR apache#420, on getting control on the logging. This changes disables Pax Exam's preference for Pax Logging, and changes it with Logback (in the latest SLF4j 1.7.x compatible version). With this change, SLF4j and Logback are now available for both the unit tests and the pax exam tests.

Configured explicit versions of all 'mavenBundle's declared in the ComponentTestBase, as otherwise Pax will depend on Maven's LATEST, which is not always compatible.
