Add stats js files to static dir

Add stats js files to static dir

build.chromium.org does not use https, so masters
that serve over https will soon need a more secure
source.  Add these to chromium-build for convenience.

Examples of current use:
http://build.chromium.org/p/chromium/stats/Mac
http://build.chromium.org/mochikit/MochiKit.js

LGTM.

If we can get all of the masters to get all of their static HTML, CSS, and JS
from chromium-build.appspot.com so they're only stored in exactly one place,
that would be awesome.

Aaron, could you ping this review when you get a chance to upload this to
appengine?

Ping.  Still waiting on a chromium-build push.
