// This is the GTK implementation of the bookmark bubble, the dialog box
// presented to create or edit a bookmark.  There can only ever be a single
// bubble open, so the class presents only static methods, and handles the
// singleton behavior for you.  It also handles the object and widget
// lifetimes, destroying everything and possibly committing any changes when
// the bubble is closed.
