* Fix chat filter button
Oh look, the popup code was copy pasted between chat filter and channel selector.
Hilarious.
Anyways same stuff as 995f506aaf. I pulled it all out into a base class so NO MORE COPY PASTE.
Fixes#22360
* Remove all further EnableAllKeybinds buttons.
Fixes#22346
Yeah none of these are valid use cases, why is this set...
* split admin chat into new channel
* add ability to play audio when a chat message is received and add audio to admin chat
* give client control of AdminChat sound and volume + suppress sound for senders
