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.
