Zope-interface

------------------

- Add support for Python 3.4.

------------------

- Update ``boostrap.py`` to version 2.2.

- Add ``named(name)`` declaration, that specifies the component name, so it
does not have to be passed in during registration.

------------------

- Fix a bug where a decorated method caused false positive failures on
``verifyClass()``.

------------------

- Fleshed out PyPI Trove classifiers.

------------------

- Add support for Python 3.3.

- Restored ability to install the package in the absence of ``setuptools``.
