Updated gist patch to also allow the setup info page to work as well.

For the second patch you have to do it there. If you try to do it in the same place as the first page the prepend gets duplicated (even though it seems to work a bit). The check is in class-bootstrap.php to see if it should show a directory or the info page. It passes to class-context.php is_info_request() and compares REQUEST_HREF from class-setup.php against PUBLIC_HREF in the same file. Since the latter is already set we just had to patch the first to match as needed. We used the same method of detecting how the url is being accessed in both routes in order to ensure it works via both url addresses without issues.
