Improve AOSP Download/Upload animation

This increases the number of png required for a full download/upload animation cycle.

ParanoidAndroid icons.
services: don't clear wallpaper when SystemUI

When we restart SystemUI (or the user), sometimes
the wallpaper would get cleared. This patch just
captures its originating component and
if that is our SystemUI component, ignore the event.
