I've added support for 7TV, BTTV, FFZ emotes without relying on the native extensions, while improving support for those extensions if all of them (or some) are installed. Among with a few minor fixes.

This extension adds custom Twitch emotes and animated username paints to Twitch
chat. It runs only on twitch.tv, injects emotes into chat messages via a content
script, and adds a ":" autocomplete for emote names in Twitch's native suggestion
popup. It communicates only with Twitch and its own backend (api.thisge.app,
events.thisge.app), stores only local interface preferences, and collects no
personal data. No account is required to use or test it.
