Reland part 3 of 4: Modify blink users so they use blink images.

Reland part 3 of 4: Modify blink users so they use blink images.

Now that the image resources that blink depends on are in the blink
repository, we depend on the blink resources directly, delete the ones
in the chrome tree, and use these resources in the html_viewer.

[This reland also contains a fix to the generate_blink_resource_map.py
file so that its generated code uses unsigned chars, which should
hopefully fix the Win8 gn bot.]

So this line accounts for about 1MB of the 1.5MB sizes regression on Mac in
http://crbug.com/471609 (i.e. deleting this line and rebuilding, Google\
Chrome.app goes from 179152kB to 178136kB

I think this must be a packaging error. WebKit/public/default_200_percent/blink
has only 1kB of resources but this 200_percent.pak file is full of js/css and
(looking at blink_resources.grd) a bunch of .wav files? There are now two copies
of all of these being bundled into Chromium.app on Mac.
