Patch for bug #80986 - bookmark window

[Damon Chaplin <damon ximian com>]

I've added a patch to:

    http://bugzilla.gnome.org/show_bug.cgi?id=80986


The DnD code hadn't been ported from 1.4.

I had to rewrite it a bit since we now use GtkTreeView.
It is a little hackish as it has to keep the list store in sync with the
nautilus list of bookmarks. But it seems to work OK.
