Gensuitemodule needs an overhaul, if possible before 2.3.

Things that need to be done:
- Use more MacOSX-compatible ways to get at the AETE. Donovan Preston posted a note on how to use the ascr/gdte call. There's also some interesting-looking calls in the OpenScripting framework.
- Distinguish between running while building a distribution (things go into Lib/plat-mac/lib-scriptpackages) and running as a user (things should go into site-packages).
- Allow for non-interactive use. Main problem is that some suites need a name-mapping, and there's undefined enums to be catered for.
