/**
Future handshake/connection procedure:
- GET all tts config data
- Continuous connection to server to receive commands from tom & send logs/errors (med priority, though tough task)

Ideas:
- Filter messages by badges.
- Speed up TTS based on message queue size?
- Cut TTS off shortly after raid (based on size of raid)?
- Limit duration of TTS
