Subject: [PATCH] Making babel able to run in node_modules directory (while
 still ignoring node_modules packages)

In case if app is installed by npm install <git tarball url> which is very comfortable thing (postinstall hooks, automatic package installation and so on) babel is unable to run over packages, e.g.
```
 ~/node_modules/some_app$ node-babel app.js
  ```
 is crashing as babel do not want in node_modules directory.

 relative path gives ability to check whether lib is in node_modules _relative_ to current app, so that if app is ran in node_modules by itself it will not be captured.
