Subject: [PATCH] [FacebookBridge] Handle summary posts

Previously summary posts were ignored which resulted in the last
two posts not showing up in the feed (the latest two are shown in
the summary post).

Now summary posts are treated like regular posts, returning them
as part of the regular feed.
