Add new WaveView widget to framework and integrate into LockScreen.
This adds a new "Energy Wave" widget to the internal widgets and
integrates it into LockScreen.
ValueAnimator needed a slight modification since it expects to
be run inside of Activities with a Looper. Additionally, this adds
an API, removeAllUpdateListeners(), which is needed to properly
recycle ValueAnimator objects.
Some minor code cleanup and UI tweaks after review.
Changed delay timeout from 1.3s to 0.5s.
