Enhance: Twitch multi-streamer support and fix timer listall

- Twitch add: multiple streamers via comma separation
- Twitch add: optional discord channel (defaults to current)
- Twitch remove: multiple streamers via comma separation
- Twitch listall: new command showing all server streamers (admin)
- Timer listall: fix SQL error by removing invalid JOIN
