Log Message:
Update zope.interface to 4.1.2. Reset maintainer, as sifu tells me he no longer
uses zope nor pkgsrc.
Changes:

4.1.2 (2014-12-27)
Add support for PyPy3.
Remove unittest assertions deprecated in Python3.x.
Add zope.interface.document.asReStructuredText, which formats the generated
text for an interface using ReST double-backtick markers.

4.1.1 (2014-03-19)
Add support for Python 3.4.

4.1.0 (2014-02-05)
Update bootstrap.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.
