SilentSpike d3ce75daef Spectator overhaul (#5171)
- Overhauls the spectator module entirely to share a similar UX to BI's "End Game Spectator" while maintaining some of the extended flexibility of ACE Spectator.
- Simplifies spectator setup by reducing the number of settings. More advanced setup is still possible via the API functions provided.
