Add support for images next to list of blog posts on landing site #15
Description
A chapter has asked if there can be images next to the blog posts in the "Recent Statements" section of the landing page.
This can be done by adding an image to the html for posts on the landing page with the source being post.image.
The hard part is making it look nice.
We also need to decide what to do if there is no image specified in the post's front matter. Right now, there post will use the default image specified in the _config.yml file.
