And reallysimple, the feed reader FeedLand and other apps are built on, now understands rss.chat conversations

Until today it read our feeds but quietly discarded the two pieces that make a conversation a conversation -- which post a reply is replying to, and where a post's replies live. So an app reading rss.chat through it saw a flat list of posts and no threads, with nothing to indicate anything was missing. Fixed and published. Anything built on reallysimple gets threading by updating the package.
