- Add an API test for datatype-defined composite uploads - including exercising newline conversion and the space_to_tab parameter.
- Add a test decorator skip_without_datatype to mirror skip_without_tool for this test, improve both decorators.
- The ftype parameter in the composite test tools does nothing - drop it and drop it from the XSD spec.
- Slightly improve the documentation for these composite_data elements in the XSD.
Adding file test/functional/tools/metadata.xml demonstrating how to check output metadata - this file also demonstrates setting metadata on uploaded datasets and verifies both of these functionalities. Checking output metadata is only available for new API driven tool testing.
