        Initial check-in for <rdar://problem/3154486> - Supporting FTP directory listings in the browser

        Development has taken place on both Leopard and Windows (windows enabling patch will follow shortly)
        Support will only exist on platforms whose network layers (ie, ResourceHandle) support piping the raw
        FTP Directory data into the engine.  

        This is known to include Leopard, Windows, and CURL based platforms - probably others
        Known incompatible platforms include Tiger.

        The FTP listing page is built in HTML.  An external HTML document can be provided as a template for the 
        directory listing.  This document is parsed, and expected to have a <table> with a certain class in it.
        As FTP directory listings come in, each entry is added to this table as a row.

        If no HTML template is provided to work with, a very basic empty document is hard coded that contains only 
        this special table.

        Upgrades to the look and feel of the directory listings can take place largely in this HTML template which,
        admittedly, is conspicuously absent in this initial checkin
