Add ContentLoadingProgressBar support

ContentLoadingProgressBar allows developers to follow the policy for loading content
laid out in the style guide. The progress view will only show if MIN_DELAY
passes before the view is hidden. The progress view, if shown, will always
show for at least MIN_SHOW_TIME ms.

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.
