- 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.
Add example tool test for composite data (worked with Twill based test framework prior to this commit, works with API based framework as a result of this commit).
