Update json2.js

[mgibbs189]

json2.js and json2.min.js were sync'ed from the official GitHub repo:
​https://github.com/douglascrockford/JSON-js

The most noticeable difference is a check to ensure that JSON is an object. There's also readability improvements to some of the ternary operators.

Have a look at the JSON3:

JSON 3 is a polyfill compatible with nearly all JavaScript platforms. It is a drop-in replacement for JSON 2 that uses feature tests to detect broken and incomplete native JSON implementations, supports asynchronous module loaders and has-aware optimizers, and is built to specification standards.
JSON 2 is an older, alternative polyfill by Douglas Crockford.

Updates the earlier patch file with the latest copy of json2.js.

Moving to json3 is off-topic for the ticket about updating the existing library. Discussions about moving to a new library, like JSON3, should happen on their own ticket.

There's a couple open prs for JSON2 that should be tracked in case they get merged before the 4.4 cycle ends.
