Update interpolators and durations for state animations

When we enter overview (overview appears, workspace disappears):
- Workspace scales down from 1f to .8f with OvershootInterpolator(1.2f) at 200 ms
- Workspace fades from 1f to 0 with OvershootInterpolator(1.2f) at 200 ms
- Overview scales down from 1.33f to 1f with OvershootInterpolator(1.2f) at 200 ms
- Overview fades from 0 to 1f with OvershootInterpolator(1.2f) at 200 ms

When we exit overview (overview disappears, workspace appears):
- Workspace scales up from .92f to .1f with DecelerateInterpolator() at 200 ms
- Workspace fades from 0 to 1f with AccelerateInterpolator() at 200 ms
- Overview scales up from 1f to 1.1f with AccelerateInterpolator() at 180ms
- Overview fades from 1f to 0 with DecelerateInterpolator(1.7f) at 200 ms

Parallax while the finger moves: Workspace translates half the distance as the shelf
