Add new Android 7 wallpapers

Add new wallpapers designed for the Android 7 release. The wallpapers
come as png's because they will be used in overlays for the framework
for the default wallpaper, and the default wallpaper is a png on
Android 7.

Thumbnails have been modified locally and should really officially come
from the content team.
They were created with ImageMagick's
    convert -resize 768.
