Make the file chooser entry optionally capture Escape and emit a signal. Make the file chooser widget hide the entry on that signal and go back to the path bar. This gives us a two-level undo: location entry -> path bar -> dialog close. When the location entry is permanently displayed in the header for save mode, we still let the first Escape close the dialog.
