Log username in Apache access logs
This is a piece of middleware that reports the logged-in user back to Apache. This should cause the logged-in user to be present in the apache access log. Put it in `settings.MIDDLEWARE_CLASSES` after `AuthenticationMiddleware`. This has been tested with mod_python but does [not work with wsgi](http://groups.google.com/group/modwsgi/browse_thread/thread/8785a99d4ba7ee99).
