Chakracore: jsrt: Help US to update documentation and samples

[obastemur]

Recent changes, we have differences between ChakraCore JSRT docs and the actual implementation. (including the new API I have recently added)

[optional, bonus]
++ add more samples to https://github.com/Microsoft/Chakra-Samples/tree/master/ChakraCore%20Samples (move sample.cpp from this repo's test/native-tests/pick-a-sub-folder and add code comments)

EDIT: more detail and typos

[Announcement]

If I have time wednesday I'm pretty good at writing documentation and samples if no one beats me to it by then.

To give some extra pointers, we miss docs for modules APIs in ChakraCore.h and debugging APIs in ChakraDebug.h. Would appreciate PRs to https://github.com/Microsoft/ChakraCore-wiki for docs.

Samples go to https://github.com/Microsoft/Chakra-samples.
