[Gtk-sharp-list] IDisposable

[adam treat]

Ok, we tried to have the Dispose method unregister the objects in the hash, but there was a
problem with Monitor locking and the GC:

  ~Pixbuf ()
  {
    Dispose ();
  }

  Dispose ()
  {
    UnregisterObject ();
  }

This should work, but when the program thread tries to access the hash for introspection and the
GC also tries to access the hash, the program freezes, regardless whether it is lock()ed in both
threads.
