gtk_tree_model_iter_previous()

[Murray Cumming Comneon com]

As mentioned here:
http://bugzilla.gnome.org/show_bug.cgi?id=128058

It would be nice to have a gtk_tree_model_iter_previous() as well as the
current gtk_tree_model_iter_next(). Totem has an implementation, though I
guess it's significantly slower than gtk_tree_model_iter_next():
http://cvs.gnome.org/lxr/source/totem/src/totem-playlist.c#146

Thoughts?
