Added Json.value(object) Method and JsonSerializable Interface

[pbi-qfs]

To create JsonValues directly from complex java objects. Extends PR #80

@pbi-qfs why would char[] objects become JSON strings? Seems counter-intuitive, even though the conversion always works. This is creating a single exception to the "an array goes in, an array comes out" pattern.

@mafagafogigante you're right, maybe I wrote to much eclipse compiler stuff, so in my head, char[] and Strings became equal...

I gladly changed this, so the API is more consistent.

[bernardosulzbach]

I understand, but the library should not cause surprises. And while a string is a string, a char[] is an array.

I don't think I will use this stuff anytime soon, but I understand that there might be use cases for it.

Additionally, it has improved a lot from your initial proposal. As long as it doesn't degrade parsing performance (which it doesn't), I am OK with it. Good luck.
