We need to pass different options and this seems cleaner at this point.

In order for docs.min.js to keeps all comments, we don't pass `compress`.

We can check for browser compatibility on lint time now.

This is so other plugins can use it too.

This way, it's run for us automatically after `docs-compile`.

* use .babelrc.js, compile bundled/non-bundled with loose mode

* add back helper, exclude typeof transform

`$npm_config_tmp` is a non-existent variable.
Also, use double quotes since single ones don't work.
Finally, git ignore the temp file.

Gemfile was missing. Couldn't compile documentation when using npm.

Specify `--source-map-contents true` for node-sass and `source-map-inline-sources` for clean-css.

Without this, the sourcemaps weren't found.
