dev-python/namespace-zope: New package to handle namespace

Add a new package that installs __init__.py that enables setuptools
namespace processing for zope packages. This makes it possible to remove
the hacky *.pth files installed by various zope packages currently while
preserving namespace package compatibility with Python 2. This in turn
should fix some of the issues with namespace handling.
