====================
- Port 3.4.1a1 to trunk
- Do not use unicode strings to set the application server in the virtual
host namespace. This caused ``absolute_url`` to create unicode URL's.
- Add a traverer for ``++skin++`` for XMLRPC skins (``IXMLRPCSkinType``).
This also means that the normal ``++skin++`` namespace handler is only
bound to ``IBrowserRequest``.
- Resolve the dependency on ``zope.app.applicationcontrol`` by importing the
application controller only if the package is available.
