Live

Added

• schema.org LiveBlogPosting structured data — the markup behind Google's "LIVE" badge. live/_feed.twig prints it: coverage start and end times from the post's state, and the latest updates as BlogPosting items. craft.live.schema(feed) prints it from your own templates, with limit, extra and seomatic options.
• With SEOmatic installed, the object goes into SEOmatic's JSON-LD container instead of its own script tag.
• StructuredData::EVENT_DEFINE_LIVE_BLOG_POSTING, to add a publisher, an about event or anything else before the object is printed.
