- Use vertical layout for Graphviz-generated class inheritance diagrams (to get the old behaviour back, change the rankdir arguments from "TB" to "LR" in the inheritance.py script;

- Do not generate module-level inheritance diagrams anymore;
- Correct a few ReST typos in `newevent.py`, `expando.py` and `buttons`;
- Include a toctree ReST reference to `classic_vs_phoenix.txt` in the `MigrationGuide.txt` document, to stop Sphinx complaining about it.
