Remove JythonCommandSpec as it's not required on Jython 2.7 and setuptools no longer supports anything 2.5, but had to test for 'Jython on Windows' in two other places

Relicense the package as MIT license. Drop licensing as PSF and Zope as neither of those licenses grant authority for use outside their respective projects. Vendored projects are licensed under their respective licenses, currently MIT for six and Apache v2 for packaging. Fixes #132.

Merged in svetlyak40wt/setuptools/svetlyak40wt/make-194-same-level-header-as-other-vers-1453106898145 (pull request #171)

Make 19.4 same level header as other version numbers.

Invoke import on importlib.machinery directly. Access an attribute to force import in delayed-import environments. Fixes #487.

The problem was that restructured text considered 19.4 is a sibtitle to "CHANGES".

Possible fix for #207

Remove JythonCommandSpec as it's not required on Jython 2.7 and setuptools no longer supports anything 2.5, but had to test for 'Jython on Windows' in two other places

in sys.path.  This ensures that lookups in __path__ will be the same
as sys.path resolution.

This also adds a replace argument to Distribution.insert_on meant
to be used with the replace argumen to WorkingSet.add.  This ensures
that new sys.path entries added via WorkingSet.add are inserted at
the beginning, rather than appended to the end.  This is necessary
for consistency with the above change, and kind of makes more sense
anyways.  This means that if a Distribution is added to a WorkingSet,
that replaces a different version of that Distribution, the new version
of that Distribution will have its location first on sys.path.
