Update icon badges to match spec

Browse Source 
- Size defined as percentage of app icon size
- Width changes when there are 2 or 3 digits (round rect)
- Offset slightly away from the app icon
  - Had to move drawing to BubbleTextView instead of
    FastBitmapDrawable
- Hide badge when dragging and while popup is open
- Tweaks for some color/text parameters
