Automatically build library dependencies

I've made a fork which downloads and automatically compiles glew and glfw for the target architecture as part of a normal `npm install`. This makes the package a normal node dependency that you can simply install, as opposed to a difficult source of confusion and platform specific concerns.

As part of this work, I ripped out the AntTweakBar dependency, since I don't need those features anyway. Nevertheless, you might get some inspiration from the other stuff I've written. Feel free to pull in full or part or close this request outright :)
