Revision 1732517

Several improvements of the integration/unit tests:

- preconfigure the right OSGi HTTP port for all integration tests using
  runproperties instead of doing this from the test setup (this shaves off a
  couple of ms per test run);
- remove the unit/performance/broken/... labels from the TestNG tests as they
  aren't used consistently and do not give any additional information;
- do not baseline the org.apache.ace.test bundle, as it is only used for the
  (integration) tests and not shipped as part of the binaries;
- some formatting applied where necessary.
