library instead of the zipfile hack.  This is because you can't just

compile, marshalled, compressed, and then inserted into the library's
data section with a certain symbol name.  Additionally, a new Importer
was needed to allow python to get at the embedded python code.

Small additional changes include:
- Get rid of the PYTHONHOME stuff since I don't think anyone ever used
