Currently the partners RSS feed of a blog excludes posts shared from another blog, including verticals. This PR includes shared posts from within the blog group (main blog + verticals).
Currently for FBIA, we pull out the first asset from the postbody & insert it at the top of the article, then render the rest of the article (without the first asset).
Adds image attribution params to FBIA blocknode rendering/templates:
Tweets rendered on Google newsstand and Facebook Instant Articles will appear taller (260px instead of 159).
Test Duration: 11/6/2017 - 11/27/2017
Added theroot.com to claimed domains in Facebook Business Manager so that verticals are also included in the Production/Published articles.
