Add ability to mix to mono

[Darxus]

Binary package hint: pavucontrol

Please add the ability to mix to mono. Preferably as conveniently as I can enable and disable muting (maybe in the indicator applet?).

I often come across audio on the internet (youtube) where it's obvious the creator never listened to it through headphones - the left and right channels are horribly imbalanced. It would be nice to just listen to that stuff in mono.

Status changed to 'Confirmed' because the bug affects multiple users.

I've just duped 485694 to this one. The reporter of that one wants basically the same functionality; although their need is because they have one speaker in each room, so they don't need the ability to rapidly change it.

It would be even nicer if I could pick between mixing to mono, or listening to only the right or left channel in both sides of my headphones (sometimes one channel is garbage and the other is decent),.
