This is a complete re-write of newsriver, simplifying the entire engine
drastically and adding traditional feed reader capabilities. By default
the app loads in the traditional format, but you can visit `/river`
to get the never ending river of news.
Right now it's still very early, but the following functionality is
supported:
- Adding of RSS feeds
- UI/Serverside polling of RSS feeds to keep them in sync
- Read/Unread tracking per feed
- A single API that powers the entire system
- HTMLx for the majority of UI updates
