Addresses #33 and changes the UX to be more like AOSP. The handle will now be hidden by default until the user scrolls the view, and it will fade in and out at appropriate times. Because the view isn't set to GONE, the user can still use the invisible scroll track to jump straight to a section of the list - lemme know if I should fix that by making the view GONE until the user scrolls.
