* Deadlock detection: the chatbot handlers will spin off a background goroutine
to ping DMs at itself and test for responsiveness. If the echoes don't return
for a minute, issue a /api/shutdown command to the HTTP server to force a
reboot.
* New admin API endpoint: /api/shutdown, equivalent to the operator '/shutdown'
command sent in chat. Requires your AdminAPIKey to call it. Used by the chatbot
as part of deadlock detection.
* Adjust some uses of mutexes to hopefully mitigate deadlocks a bit.
* Do Not Disturb: if users opt to "Ignore unsolicited DMs" they will set a DND
status on the server which will grey-out their DM icon for other chatters.
* Bring back an option for ChatServer to notify you when somebody begins watching
your camera (on by default).
* Automatically focus the message entry box when changing channels.
* Lower webcam resolution hints to 480p to test performance implications.
* 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.
* In case the user has remembered their camera/mic permission and the
Share Webcam button is able to list their devices before they go on
video the first time, we can (try to) select their favorite devices
(by name) that they used the last time they were on.
* Added support for Webhooks and you can configure a Report Message hook
to let users report messages on chat.
* Add /reconfigure command to dynamically reload the server
settings.toml
* TODO: documentation for the webhooks.
