Cleaning up during uninstall and submitting Portfile

Actually, this is what I'm already doing. However, at run-time, the package
creates files in these directories, so Macports doesn't remove them. That's
why I was asking about something like a post-uninstall hook, which can
remove these (possibly) nonempty directories, and remove the user account
created during package installation.
