Wish JSON ToPrettyString order

[alwaysbusy]

When we now do this, the order in which map values are entered is not preserved.

I think this little change in the library would keep the order:

this.nameValuePairs = new HashMap<String, Object>();

to

this.nameValuePairs = new LinkedHashMap<String, Object>();

Why is the preservation of the order of the name/value pairs important? Relying on the order of the pairs goes directly against the JSON specification which says "An object is an unordered set of name/value pairs."

I know the Json specs, but it would be nice for ToPrettyPrint (used for documentation for example): e.g. the id is always the first and not somewhere in the middle of the json file.

I guess that this library makes this change: https://www.b4x.com/android/forum/threads/json-simple2-keep-the-json-order.80589/#content

I prefer not to add it to the official library:

1. It means that all JSON maps will be LinkedHashMaps and it will have a small performance overhead. It is possible that in some use cases the performance penalty will be significant.
2. It can only be done in B4J.

I tried the above mentioned lib, but it had the same result. I do understand why you do not want it in the official lib so I will build my own as for my documentation app this is really needed.

Json library source code is attached.

Very cool of you to share this @Erel! Will save me quite some time. Thanks!
