Title: Disable the "apply" button if there's nothing to apply.

It's a little confusing that you can jam "apply" when there's nothing different to actually write, and you have no way of knowing if the settings that are used for "sync" are up-to-date or not. This disabled the "Apply" button when there aren't any changes.
