[Gtk-sharp-list] PATCH: samples/TestVfs.cs

[Tamara]

This is my first patch so I hope this goes okay but I just got Gtk#
1.9.0 so I would have GnomeVFS support and I noticed that the
TestVfs.cs sample script reflects some previous incarnation of
GnomeVFS support (class and method names have changed). This is a
minor patch against CVS (the file hasn't changed since 1.9.0).

My apologies if this is not in the correct format (it is a unified diff though).
