Echo JS 0.11.0

Indeed, I don't think CoffeeScript is still relevant.
But we have to admit that it spun a lot of innoation in the JavaScript community in the past, leading to the whole ES6 new syntax. A lot ot remarkable projects (Atom comes to mind) are built using CoffeeScript.

But now that ES6 *is* here... well... It looks like it's yet-another-language-that-compiles-to-JavaScript. With nothing much to add, I'm afraid.
