DankChat

- DankChat now uses Twitch's new EventSub backend instead of the deprecated PubSub backend. This allows moderation messages to be more detailed and new Twitch features to be implemented sooner compared to before.
- Added profile avatar badges when shared chat is active
- Added quick option to toggle input on/off
- Added setting to also include the stream category in bottom info text
- Fixed zero width emotes not being centered
- Added new open source licenses notice in the about section
