0 in an array is parsed into null

Expected behavior

I’m running into a crucial issue where if I enter this JSON, the “0” in the array turns into null. The expected behavior is that it should remain a “0” and be of type number, as opposed to type null. This appears to be related to #159.

Actual behavior

What actually happens is the the “0” gets turned into a null.

Steps to reproduce the behavior

Simply go to the demo here: https://rawgit.com/json-editor/json-editor/master/docs/demo.html

Paste in the JSON below, and click update form. You’ll find that the 0 has been parsed into null.

{ "array": [ 2, 0, 1 ] }

This workaround works for me.

I like the idea. Either in the README and/or the wiki (a link to the wiki may be enough).
