Enhancing FreshRSS with rssCloud Support

I’ve been using FreshRSS for a while as a backend for NetNewsWire and decided to finally create an extension to add rssCloud support. This not only does what you’d expect: subscribe to feeds that support rssCloud <cloud> elements. But it also supports subscribing via HTTPS when port 443 or the protocol “https-post” are specified. It even looks for the latest and greatest <source:cloud> element from Dave Winer’s source namespace. But wait, there’s more! Since FreshRSS supports subscribing to an OPML file, I’ll even look for a <source:cloud> element on OPML files and subscribe for real-time updates. This is super handy if you want to subscribe to the OPML feed for the super cool I RSS directory!
