Zope-dublincore

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

- Rename the ``zope.app.dublincore.*`` permissions to
``zope.dublincore.*``. Applications may need to fix up grants based on the
old permissions.

- Add tests for ``zope.dublincore.timeannotators``.

- Add not declared dependency on ``zope.lifecycleevent``.

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

- Remove the marker interface IZopeDublinCoreAnnotatable which doesn't seem
to be used.

- Make the registration of ZDCAnnotatableAdapter conditional, lifting the
dependency on zope.annotation and thereby the ZODB, leaving it as a test
dependency.

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

- Add missing dependencies.

- Get rid of any testing dependencies beyond zope.testing.

- Include browser ZCML configuration only if zope.browserpage is installed.

- Specify i18n domain in package's ``configure.zcml``, because we use message
IDs for permission titles.

- Remove unused imports, fix one test that was inactive because of being
overriden by another one by a mistake.

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

- Declare dependency on zope.datetime.

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

- Test dependencies are declared in a `test` extra now.

- Fix: Make CreatorAnnotator not to fail if participation principal is None

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

No further changes since 3.4.0a1.
