dataone 2.1.0

The dataone version 2.1.0 release adds new functionality to support downloading,
modifying and updating DataONE packages. Also getMetadataMember() has been added
that can be used to identify the metadata object for a DataPackage. The getPackage()
method now accepts pids for data or metadata object, so that the resource map pid does not
have to be known to retrieve a package.

Bug fixes include fixes to the query() method when results were incorrectly converted,
and incorrect results returned for multi-valued Solr fields.
