Updated py-setuptools to 29.0.1.

v29.0.1
-------

* #861: Re-release of v29.0.1 with the executable script
  launchers bundled. Now, launchers are included by default
  and users that want to disable this behavior must set the
  environment variable
  'SETUPTOOLS_INSTALL_WINDOWS_SPECIFIC_FILES' to
  a false value like "false" or "0".

v29.0.0
-------

* #841: Drop special exception for packages invoking
  win32com during the build/install process. See
  Distribute #118 for history.
