Oh the vast sweeping changes, and they're not even close to complete, but

things compile and most things run so this is a good time to checkpoint.
Let me recall:

- Refactored the whole scene deal.
- Revamped the XML parser stuff (now uses Digester).
- Rethought the tile management.
- Started tile bundle stuff.
- Wrote some tests.
- Did a bit of Mike-ification.

Onward and moreward.
