Improve AOSP Download/Upload animation

This increases the number of png required for a full download/upload animation cycle.
These new png makes the animations much smoother.

PS2: Improved it. Tweaked xmls. Looks better! I think. I didn't rename them though. So, it's all out of order number wise--
other than that--should be better.

PS3: Should be good to go. Named the pngs accordingly, fixed HDPI and XHDPI to match. Bam.
