remove coffeescript?

[jimmywarting]

I found stuff like:

shelljs/package.json

Line 66 in b4daff5

"coffee-script": "^1.10.0",

is it still being used?
how about dropping support for for coffee script entirely?

(besides it's deprecated CoffeeScript on NPM has moved to "coffeescript" (no hyphen))

This is still used by shjs. I'm planning to remove shjs (see issue #500), but I'm not sure what the best deprecation strategy is.

I think "coffee-script" and "coffeescript" have different min node versions. I should double check what the min node versions are though and see if we can upgrade this dep.
