alter mouse button 2 clicks to behave like mouse button 2 clicks for lp bug #898611.
This solution was taken from gvc-channel-bar.c in gnome-control-center. The idea of cribbing from g-c-c came from Christian Giordano in duplicate lp bug #932919 where he suggested "using the same behavior the volume slider has in the Sound System Settings."
