* 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.
* 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.
* Add configuration system and default public channels support
* Add support for multiple channels and DM threads with users,
with unread badge indicators. DMs rearrange themselves by
most recently updated on top.
* Responsive CSS to work well on mobile devices.
* Reworked full screen CSS layout for the chat.html, still using Bulma
components with some custom CSS Grid.
* Duplicate username handling: server can push a new username to change
the client's selection.
* Who List sync between clients.
* Local video casting works so far - plays back your camera in the local
feed. Your video broadcasting boolean is synced to backend, which
lights up the video button in the Who List.
