Fix animation bugs, stop disabled sweep touches.

Change sweep drawables to crossfade correctly between states, and
work around 4946591 by nesting container one level deeper.  Also wait
until first layout pass is finished before applying LayoutTransition.

Prevent touches from reaching sweeps when chart is disabled.  Also
bring back log scale for data.
