Do not conflict with ES6 module keywords

[mrinterweb]

I have been encountering issues lately that are using Square's ES6 module transpiler. The issue is that ES6 modules make use of some new reserved words "import" and "export". Naturally, this doesn't play nicely with the current iteration of CoffeeScript.

Please change the words import and export in CoffeeScriptRedux to something else.

We'll reserve import/export once they're reserved in a final version of the ECMA-262 spec.
