[nautilus-open-terminal] Use custom SFTP URI parsing routine

[Christian Neumair <cneumair src gnome org>]

commit 386a949af468a9af9c4a4feae1186c51422ec79c
Author: Christian Neumair <cnmeumair gnome org>
Date:   Sat May 23 09:49:11 2009 +0200

    Use custom SFTP URI parsing routine
    
    Based on launchpad #333462, we use our custom URI parsing routine until
    Glib supports it, to get rid of the GnomeVFS dependency.
    Thanks to Maxim Levitsky for the implementation.
