This addresses #399

Description

Featured images for posts on blog page should link to post. The solution decided for this feature is, rather than have a toggle for whether the featured images should be links or not, this behavior will be standard. This is understood / expected behavior which was not previously included. This feature will apply to featured images for posts on the Post List ( Blog ) Page, with a featured image position of Above Header, Below Header, and In Post Content. This will not apply to 'Header Background' position setting, as this would interfere with the post meta links that are overlaying on top of the background image.

This specific PR addresses the templating changes. Styling changes can be found in BGTFW/PR#732
