Param for og:image/twitter card in front-matter

[jeremejazz]

First of all I like this template a lot. I was wondering if adding an optional front-matter parameter on blog posts for og:image / or twitter summary image would be a good idea. Something like .FeaturedImage. so you wouldn't end up sharing links with the same preview image.
What do you think. I would be glad to help. :)

@jeremejazz this is a great idea that I've wanted to implement myself for some time, but haven't gotten around to it. The aim is to have a featured image param that would be used for social media shares as you have mentioned and would also display at the top of the blog post.
