Swipe up from nav bar in OVERVIEW or ALL_APPS to go home
Add NavBarToHomeTouchController, which intercepts touches from the nav bar
region when in overview or all apps.
Swiping up from all apps translates it up and slightly fades out app icons,
then letting go springs towards home screen.
Swiping up from overview translates it to the right, then letting go springs
towards the left where it lives in the home state.
Both cases have a strong deceleration while swiping.
