setup.py sdist/bdist is missing antd/antd.cfg (no MANIFEST.in)

This was also reported as

#19

where cfg.write_default_config() fails.

The default antd/antd.cfg file is in GIT but is not installed by setup.py in some cases (e.g. sdist, bdist_rpm) since it is not part of the file manifest. It is referenced as 'package_data' in setup.py but this not not sufficient.

I believe the fix involves adding 'include antd/*.cfg' to a new MANIFEST.in file at the top level of the GIT sources.
