Parse Status Messages to make them available in Node.js

Here my second pull request to add this.

Please note: I have done my very best to it as similar as possible to all other code. I've also extended the tests for it, but I couldn't make it pass the tests.
I've tried very long and many things, but I don't know where the problem is.

I think it's a very small issue, that I likely can solve with your help.

I hop it is closer to what you expected, this time =)
