Integrate tmi.js Into Standalone Client

[Lethalchip]

Could integrate tmi.js into either the canvas route, or the overlay route- the latter requiring the overlay to authenticate.

Create "chat integrations" settings menu. Add/remove chatters to a new permissions table and can assign them diff permissions for various settings.

Potential chat integrations: !layout !element <hide/show> <elementId> !toggle <widgetId> Etc ...
