Need minor release on npm

[gangstead]

I've merged 8 pull requests in the last couple days fixing some bugs and adding some features. No breaking changes so I think it's time for a minor release.

@indexzero @jcrugzz @indutny
You three are the owners of the npm package. Can one of you either add me as an owner:

> npm owner add gangstead

Or do a minor release:

> git pull
> npm version minor
> npm publish
> git push

Please and thank you.

v0.3.0 was published. Thanks for the good work!
