Add ability to automatically test FTP directory parsing.
One idea is to:
-Have DRT use it's own FTP directory template that is easily dumped in layout test formatting.
-Put the FTP directory listing tests in their own PHP files that webkit-httpd could host and send back with the appropriate MIME type.
-Have a parent frame run as an http test that sets up DRT, and the directory listing hosted in an iframe
Another possibility is to add a webkit-ftpd and make a special LayoutTests/ftp directory, and have DRT have a set behavior for ftp:// urls
