==================
- There is no direct dependency on zope.app.component anymore (even in
the tests).
- Moved the publicationtraverse module to zope.traversing, removing the
zope.app.publisher -> zope.app.publication dependency (which was a
cycle).
- Moved the DefaultViewName API from zope.app.publisher.browser to
zope.publisher.defaultview, making it accessible to other packages
that need it.
