[Distutils] Import extensions from zipfiles (windows only)

[Thomas Heller]

I have a first working version of an importer which can import extension
modules from zipfiles, avoiding to unpack them to the file system.
License is still LGPL, unfortunately.

Subscribers to the py2exe-users list already know that it uses this code
which simulates the windows LoadLibrary call:

It works in simple cases, the only ones that I have tested so far.

Shall I publish it for experimentation?
