Live Volume Steps [1/2]

lvs: transitioned volume steps volume normalization.

-This calculates an equivalent volume ratio for the new
volume steps.

-example: Volume steps are set at 60. Volume is set at 5. That is
very low volume. Then volume steps are switched to 5. Now you
are instantly in a state were your volume steps are 5 and your
volume is 5. That's full volume! This fixes that issue.

-So it basically keeps the volume from jumping around while your
changing volume steps. It may be a little lower but should be
very close.
