JSON support for BigInt in Chrome/V8

[Ranando King]

Don't get me wrong. I didn't suggest a means of extending JSON. I suggested
a means of consistently and easily reversibly serializing anything that is
not natively handled by JSON already. I think JSON is a fairly complete
syntax for most purposes. I wish it had a reference type so that recursive
structures could be encoded as well, but the suggestion I've just made can
even be used to encode that.
