Precompile using babel before publishing

[kevinsawicki]

This pull requests publishes a babel-ified version of index.js so this module can be used in old node versions that don't support ES6 stuff.

Also adds a dependency on es6-promise that will be a fallback when global.Promise is missing.

Ugh, I guess build.js needs to be blacklisted from eslint.

Looks like the build is failing because of the code climate token.

No CODECLIMATE_REPO_TOKEN found. A CODECLIMATE_REPO_TOKEN must be specified as an environment variable.

Weird. (Mostly because master didn't fail.) Let me add that to Travis.

[malept]

OK, this is really weird. I set CODECLIMATE_REPO_TOKEN in the Travis UI and it didn't take?

Hmm, is it private? I don't think private env vars are available to pull requests.

Do you mind allowing me access to that branch via that nifty new checkbox? I will try to mess with it when I get home.

Yup, should be enabled, feel free to push at will.

eslint only supports node 4+ so linting won't be possible on CIs using node 0.10 and 0.12
