Feed -- Bitters Social

I created a "feed" module to make the stream (as used on your an Gwen's sites) more, well, modular. It takes a JSON document and parses it (after running it against a schema just to make sure the necessary fields are there). This could lay the groundwork for Bitters websites "talking" to each other -- making Bitters an example of true distributed social. Using the "shareable" attribute of the JSON document, it could let other Bitters sites pull the feed of other sites and display the latest contributions (in future versions). Right now, it's a proof-of-concept that is fully functional in reading and displaying the feed/stream. Next is writing without having to edit the JSON by hand. Either a command line tool or a password protected route in Bitters for publishing to the feed.
