Allows komodo cnds to be loaded by Modeshape

* NodeTypesImporter in modeshape.lib uses the latter's classloader for
  loading resources. This classloader has no knowledge of komodo.core
  hence fails to find the cnd files.

* By registering core with modeshape.lib, the former has access to core's
  classpath and loads resources successfully.
Reduces logging of all modeshape tests

* Single abstract class for configuring modeshape logging to manageable
  amount.

* All test classes should extend AbstractLoggingTest in order to reduce
  logging.
