Support for the distutils extention 'py2exe' added. Description: - If the py2exe distutils extention is installed this patch allows building standalone exe for windows - example: > python setup.py build --compiler=mingw32 py2exe - The 'out of the box' py2exe is not able to resolve the dependencies due to 'demandload'. A new helper module of scanning the mercurial package has been added. Changed: - setup.py: importing py2exe and sub classing its command class to fetch the build directory and insert the needed includes - packagescan.py: new helper module added, that scans the distutil build directory for modules to be included.
