* New "Misc" tab added to the Settings modal with options to reduce spam
and improve privacy.
* Opt in (or out) for public channel join/leave presence
notifications
* New option to auto-ignore unsolicited DMs
* New sound effects for Watched and Unwatched (your camera)
* Reduces spam so ChatServer doesn't need to tell you every time
somebody opens your camera.
* New spinner icon when opening someone else's camera.
* If their cam takes a while to appear, the video button shows a
spinner icon as feedback so we avoid ChatClient spam giving you
acknowledgement of the cam trying to open.
