ES6 modules and estree compatibility

[tobich]

@benjamn Following the esprima-fb's planned deprecation, I've put together forks of ast-types and recast which work with babel-core/acorn as parser instead. The biggest issue seems to be the incompatibility of Export and Import specifiers in esprima-fb vs estree/acorn/everybody else. As far as I understand, both definition sets cannot be included at the same time (several type names overlap). In case you are interested in pull request – what approach do you suggest? Abandoning esprima-fb altogether, or some kind of configuration/multiple main.js/other?

Please go ahead and submit a pull request for the babel-core/acorn version of the AST, and we'll figure out a way to let users choose which version to use (see #57). For clarity, you might be able to put the modified definitions in their own file, so that they just override the old definitions when the new file is evaluated.

Thanks a ton @tobich!

I am trying to get the pull request through, but the CI seems to be using really ancient npm version, it cannot install babel-core. :-(
