got the object difference calc test to work with pax exam. at least that part of the freezedry bundle works
all relevant tests now run through pax exam. tests use the pax exam test utils for configuation options.
updated the PaxExemTestUtils class to allow setting the log level for the osgi framework, and point to the testing logback-testing.xml file for framework logging
updated to get tests to run in equinox as well
updated the tests so that osgi tests are run as part of integration tests, and unit tests as normal testing
added failsafe configuration to run the integration tests in parallel
Merge branch 'feature/pax' into develop
