Aux1-4 on/off in MixerOutput module

[bsork]

http://www.sensomusic.com/forums/viewtopic.php?id=1281 got me thinking that the on/off switches for the auxiliary outputs should be available in the MixerOutput module. I like it the non-standard way that the Mute buttons behaves, in that the auxes aren't muted, but sometimes one wants everything to be muted without turning off the track.

it's more an oversight than a suggestion!
easy to implement, let's say 30 seconds?

I'll give a whole minute...

Thanks!
