Python std lib packaging missing binary modules under Windows

[neilstephens]

PyPort has the option to bundle the python standard library into install package so embedded python code can run in absence of python being installed on the host system.

The bundle logic only grabs the python lib directory. Under linux, this includes the lib-dynload directory containing the shared library part of the std lib, but under Windows, there is a separate DLLs directory at the same level as lib. Currently the bundling logic misses the DLLs directory.

Thanks @bjcarne for pointing this out ;-)
