arrayToJSON on lc server

[Ralph DiMola]

I've been using fastJson. I do a "start using" to include it as a library. To date I have not had any problems encoding an LC array to JSON and decoding it to a JavaScript array on the client browser.

let's see: in the public repo, there's the json.lcb source:
https://github.com/livecode/livecode/blob/4606a10ea10b16d5071d0f9f263ccdd7ede8b31d/extensions/libraries/json/json.lcb#L4
also, references to the "fastjson" library:

On the first day, God created the heavens and the Earth On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
