Resolve JS hint errors

Minor touch up so it passes validation
Just `bower install csv-js` and then:

```
var csv = require('./bower_components/csv-js/csv.js');
console.log(csv.parse('Year,Make,Model,Description,Price\n1997,Ford,E350,"ac, abs, moon",3000.00'));
```

If found a way that works with Node.js:
```
    (function(name, context, definition) {
        var define;
            if (typeof module != 'undefined' && module.exports) module.exports = definition();
            else if (typeof define == 'function' && typeof define.amd == 'object') define(definition);
            else context[name] = definition();
        }('CSV', typeof global !== 'undefined' ? global : window, function()
            { return CSV; }
        )
    );
```

You can also try using `this` instead of `window` ([like moment.js does](https://github.com/moment/moment/blob/develop/moment.js#L15)), but I haven't tested that.
