formatversion=2 in API requests gets a cleaner better response. It's the recommended future, so we should show it in all API requests, both on-wiki and in generated getExamplesMessages(). Related, ApiSandbox needs to support formatversion (T98083) and default it to on.

Similarly, Wikimedia wikis are transitioning to only supporting https, including api.php, so all sample API URLs that show http: as the scheme should switch to https:. The {{ApiEx}} wiki template and generated getExamplesMessages() don't show the scheme.

(We also should have shown continue= in all examples to encourage the improved continue format, but that will become the default in July 2015.)
