Package datamanager.jar without including classes from supporting jars
Currently the datamanager distribution unjars all the supporting jars it uses and packages them with the datamanager classes as a single datamanager.jar file.
Only datamanager classes should be included in this jar. Gathering the necessary supporting jars should be the responsibility of the application making use of the datamanager api.
This should make it easier to include in metacat and kepler and prevents version clashes with supporting jars.
