Fix the python-windows installer generator by making it include the .dll files in the installer. That list originally consisted only of "*.dll". When the build system was modified to generate .pyd files for the binary modules, it was changed to "*.pyd". The Subversion libraries and the dependencies are still .dll files, though, so "*.dll" needs to be brought back.
* packages/python-windows/setup.py: Add *.dll to the list of package data.
