* Custom emoji - In OStatus: `<link rel="emoji" name="coolcat" href="http://..." />` - In ActivityPub: `{ type: "Emoji", name: ":coolcat:", href: "http://..." }` - In REST API: Status object includes `emojis` array (`shortcode`, `url`) - Domain blocks with reject media stop emojis - Emoji file up to 50KB - Web UI handles custom emojis - Static pages render custom emojis as `<img />` tags Side effects: - Undo #4500 optimization, as I needed to modify it to restore shortcode handling in emojify() - Formatter#plaintext should now make sure stripped out line-breaks and paragraphs are replaced with newlines * Fix emoji at the start not being converted
