Updating a server you already run

This is the first of a kind of note you'll see here from now on: when a change matters to people running their own installs, the steps to update will live right here in worknotes. For this one:

1. Get the new rssnetwork.js and package.json from the repo.
2. In your server's folder, run npm install. The updated package.json adds one package -- the cleaner -- and this brings it in.
3. Restart the server.

That is the whole update. Nothing in your config or your database changes, and the cleaner applies to new and edited posts the moment you restart.
