Refactor files into their own packages

This refactoring touches most of the codebase but it does one simple thing: moves most of the code out into their own self-contained packages. With that in place we should be able to start implementing tests much more easily.

@gmelodie nicely done. It looks like there are a few conflicts with master that you might have to address. Overall, this structure makes the repository more organized, opening fertile ground for testing modules.
