Allow users to set different sounds per channel
We have a few bots set up on their own channels and they're constantly alerting. I'd like to be able to set them up with a different sound. Currently my only choice is muting. This way, when I'm working, I can tell if it's a coworker, where I need to immediately look and reply, a bot that is letting me know a new ticket was started, and I can look in a few minutes, or a bot letting me know the server is down, in which case I can quit.
