Patchset 1 reapplies r6843 as it was originally.  It works fine on my Linux
machine, but would presumably fail on the Windows production bots like it did
yesterday.

Patchset 1 was already approved by Eric in
https://codereview.appspot.com/6940053/ ('Add --writeJsonSummary option to gm')

Please review patchset 2, in which I copy jsoncpp's gyp into our our gyp
directory.  I have confirmed that this works on my Linux machine, and I suspect
it will work on the Windows bots.

(i.e. please review the DIFFERENCE between patchsets 1 and 2)
