Refinements for app transitions

- Use refined interpolator for most of the transitions which respond
to touch faster than a normal fast_out_slow_in interpolator.
- Tune clip reveal animation: Get rid of horizontal movement, only do
slight vertical movement, and make horizontal reveal animation faster
so there is a more staggered animation to resemble an opening paper
