Ideas taken from CurryCaster's guest page:
- 'Hear yourself' plays the guest's own mic in their headphones
(refused when the headphones box is unticked - it would feed back)
- Mute shows a clear 'the show cannot hear you' state
- 'What is happening' log: connection events plus stats every 15 s in
both directions (kb/s, loss, jitter, buffer, concealment, round trip,
candidate types). Never includes IP addresses. Kept in the page only;
the guest presses Copy and sends it to the host.
