A single repository & fixes

Please consider merging this, or parts of it:

- I've imported the history from Google Code (as little there may be).
- I've added the build scripts and files from the Google Code downloads (this was a bit of a mess to figure out how to use).
- So I've also added some instructions.
- I've fixed some bugs.
- I want to expose the whole library namespace, not just ScoreDiv.
