Metacat

adding getlogrecords to the rest interface.

changed getLogRecords to use new classes for log events

fixed bug in metacat that allowed attribute data to be appended to element data in returnfields

fixed bugs associated with crud access control changes.

implementing getLogRecords

added EventLog statements to all public methods in CrudService in preparation for addin the getLogRecords() method

added better debugging error messages for CN dev errors

added generateMissingSystemMetadata to the ResourceHandler so it is now available via a REST call.

made the test functional so that it checks that missing system metadata will be created.

mostly done with generating systemmetadata from legacy knb docs. need to write a better test and enable this through the ResourceHandler then it will be done.
