ECDR1, ECDR-5 Added a CDR OpenSearch Source which is designed to go hit opensearch sources instead of DI2E Tech Profile CDR Sources.  The logic in the 2 different source implementations should probably be combined.  Added in the initial ability to figure out what metadata to return from the atom link for the Metacard.METADATA.

Code is pretty rough but can be used to pull data from a couple of different public opensearch sites that return atom results
