* Add confirm removal on mixer channels Add confirm removal popup when the user calls the action "remove channel" on a mixer channel that is in use (receives audio from other channel or track). Set a config variable to keep track if the user don't want to be asked again. Adding a scroll on settings-general tab because there weren't enough space on the area. * Core Mixer function channel in use New core Mixer function to check if a given channel is in use (receives audio) --------- Co-authored-by: Hyunjin Song <tteu.ingog@gmail.com> Co-authored-by: saker <sakertooth@Gmail.com>
