Update version for npm release

The last pull request that was merged into master is vital for this package to work properly.  Unfortunately, it was never updated on npm.  Since it's a significant fix in terms of the methods functioning properly, it seemed correct to update the minor version instead of the patch version.  I'm happy to change it to 0.1.3 if you disagree!

Would it also be possible to get this pushed to npm if/when it's merged?  Thanks!
