From CSP-136656, client has requested that we update the Multimedia Macro to support HTML 5 video as well: "Being a developer, I see that the macro outputs an <object> tag. I would be great if you can put in a feature request for me to have Confluence include an HTML5 video macro in the future that uses the newer <video> tag. Modern browsers will like it a lot more."

This would deb a very useful feature for the more modern HTML5 standard and would go a long way to future-proof the product.
