Converting to using the Rakefile for testing. The old 'test' script is now deprecated, and I'll send an email to the dev list and update the docs to reflect that.

This still isn't the final solution, because the module structure is a
bit weird, but at least it's a starting point, and everything from here
on out is small changes, as opposed to large architectural changes.
