[Twisted-Python] Patch: Make twisted.web.distrib work with twisted.web.vhost

Here is a patch to make twisted.web.distrib work with twisted.web.vhost.

As things stand, when twisted.web.vhost calls a virtual host's getChildWithDefault, it ends up calling getChild.  As ResourceSubscription has no getChild, the render call never happens to make the distributed connection.  By returning self, we can make this happen.

On the ResourcePublisher side of things, after being called in this way (e.g. through a virtual host) request's prepath and postpath are a bit off; we fix this in remote_request.
