Summary:
Similar to the Hero image functionality. If a video URL is present in the post metadata, it will be displayed instead of a Hero image. This will be useful when highlighting videos in blog posts.
Renamed ReadMoreLink into a more generic ExceptLink which will display "Watch video" when the blog post category is "videos".
Currently there is no way of listing blog posts by categories, but it may be useful to do so later once we have a larger catalog of content.
