Port the folder selector portion of the BookmarkEditor to GTK.

Mirrors the BookmarkEditorView method, where the contents of BookmarkModel
are copied to a temporary model so changes can be discarded if the user hits
Cancel. In the GTK version, we copy not into another BookmarkModel, but into
a GtkTreeStore, which serves as a model to the GtkTreeView on screen.

Also ports the unit tests.
