bumped `directory` dependency to ~0.1.0 for better Windows compatibility...

We're having issues on Windows with the `directory` npm module that this module depends on.

In the mean time, the `directory` module has been updated for better Windows support and it doesn't depend on the `findit` npm module either (it also has issues on Windows).

This pull request bumps the `directory` dependency to ~0.1.0. All the tests continue to pass and it works for us on Windows.

Would be great if you could accept the pull request and publish a new version to NPM. Note that I did not change the module's version.
