My GTK is rusty, but I'm remembering it now.

This works, but it doesn't yet have the little triangle to expand/contract. That would require using a GtkTreeStore not at GtkListStore, and I've never messed with those. I'll probably try it tonight and see how it goes.

By the way this should apply cleanly to svn rev 71.
