Title: Fixed node ReferenceError: window is not defined

Getting an error with the current build:

```
var exports = window === void 0 ? module.exports : window;
^
ReferenceError: window is not defined
at /path/to/project/node_modules/isbn/isbn.js:227:17
```

This patch fixes the error and makes `isbn` run fine in node.
