Adds a 'choice' to the file chooser.
This is typically implemented as a combobox or, for boolean choices, as a checkbutton. You can select a value using gtk.file_chooser.FileChooser.setChoice before the dialog is shown, and you can obtain the user-selected value in the gtk.dialog.Dialog.response signal handler using gtk.file_chooser.FileChooser.getChoice.
