New fork

[rstacruz]

I've forked script.js here:

https://github.com/rstacruz/scriptjs

It adds no new functionality, but I've updated the repo to be a bit more modern. The build step was changed from smoosh to just plain uglify-js, so it should be easier to contribute.

I've also added a package.json license field (#99); the distribution script says it's released under MIT so I'm guessing it should be fine :)
