devel/py-zope.event: import py-zope.event-4.6

The zope.event package provides a simple event system, including:

* An event publishing API, intended for use by applications which
are unaware of any subscribers to their events.

* A very simple synchronous event-dispatching system, on which more
sophisticated event dispatching systems can be built. For example,
a type-based event dispatching system that builds on zope.event
can be found in zope.component.
