Adjust interpolators when swiping from overview to all apps 

- All apps content fades in quickly so that icons are opaque by the time
  they are on screen
- Recents fades out late so that we don't see it as translucent while
  the transition is continuing (the translucent icon top of tranclucent
  task view looks bad, for instance)
- Fix colored scrim that appears over recents - was using 0 to 1 instead
  of 255
