Metacat

Now that MetacatHandler creates GUID identifier mappings and system metadata, many of the tests in IdentifierManagerTest were failing that were manually creating id mappings and system metadata.
Modified testCreateMapping() and testCreateSystemMetadataMapping() to use docids that haven't been inserted to just exercise the methods....

Added a new test method testDeleteDocumentByGUID() to ensure MetacatHandler can delete based on GUID, but fall back to docid if the GUID isn't present. Modified CrudServiceTest and made some private methods public to leverage the D1 REST calls in that library (i.e. create() a doc with a GUID).

Add a method to test download a schema with included schemas.

Add a test file for XMLSchemaServcieTest.

Add a junit test file for testing the XMLSchemaParser class.

use more unique scope (document id prefix) so that getlastdocid runs successfully. use superclass generateDocumentId() method

adding fields for additional system metadata info

create another test for various i18n features including eml 2.1.1
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2495

uncomment the other test cases and make sure we do the clean up when the tests are complete (delete the uploaded documents)

use detected XML encoding when reading/writing files
use UTF-8 as default when performing queries in the DB (assume DB is using UTF-8)
remove as many PrintWriters (uses system default character encoding only) as possible and construct OutputStreamWriters where explicit encoding can be given....
