- Added MANIFEST.in to include setup_header.py in the source package.  Now gets
the version number from PKG-INFO metadata if available, or git if not, which
should handle all the cases of using sdist, pip install, or install from git
checkout.
- Improved run_test_server.py and fixed Python SDK tests to use it.
