// Temporarily disabled the GUI code. Reasons:
// - Only page-ref button works currently, IMO we should use a LyX action
//   instead, to toggle the kind of refs.
// - To change the label, IMO it's faster to delete the old one and insert
//   a new one.
// - To goto to the label, IMO it's much faster to just click on the
//   inset. That's how I've implemented it now, I hope you'll like it.
// - The more GUI code we can remove, the less work we'll have at
//   the toolkit switch.
