Add the implementation of LiveScript

[dotmobo]

Hi,

If you are interested, I added the implementation of LiveScript (http://livescript.net/).
It's a functional language that compiles to JavaScript. It was created by Jeremy Ashkenas, the creator of CoffeeScript.

Best Regards,

Morgan

Hey @dotmobo

Thank you for your contribution. It seems that everything is in place here, including tests, so I'll be happy to merge the pull request. I have one question though: did you test the generated source maps in browser?

Hi, i pushed a little correction for the livescript source map.
Now, it works under Firefox and Google Chrome. Thank you :)
