[brawaru]

Work In Progress.

This is a rewrite of StreamNotifications module that allows to send notifications about Twitch, Mixer and YouTube streams directly in Discord.

Rewrite is focused on improving the module and its database structure.
We'll also rewrite the modules used to check for the streams.
