Streams

Dobi now has a concept of a Stream, which essentially is a list of _types of content_, rather than just being able to render articles.

This allows us to build streams with various components - video, articles, fastFT, blogs, external content - and give visual/functionality treatment to each one.

To test this, I've played with fastFT, which, for the purposes of testing can be played with via this URL, http://localhost:5050/search/fastft?q=location:Japan
