add featured image paramater

[swharden]

It looks like the best way to do this is using frontmatter to define the featured image

featured_image: /path/to/image.jpg

But featured images should probably be thumbnails with the intent of using them in a list of articles. I don't think it should be used for the OG image (#2)

It would be nice to define what Google shows in search
