Implementing WebSub

So, I keep on talking about how Atom is a better idea overall than ActivityPub (due to scaling, fragility or lack thereof, and a bunch of other reasons), and how WebSub adds the much-requested push notification stuff to it, because apparently push is the only thing a lot of engineers talk about.

While this site has supported WebSub for a while, I kept on putting off actually implementing a client because I wanted to make that part of Subl.

Well, today I decided, screw it, I’m adding WebSub support to FeedOnFeeds. It seems to be code-complete, but I have yet to actually verify that it’s working. So this is a test entry to hopefully verify that.

EDIT: It works!!! Now to merge it into master and issue a PR…
