scripts lack if __name__ == '__main__'

[Jason Pellerin]

Generated scripts should wrap their call to the script entry point in the standard "if name == 'main'". Without this, multiprocessing can't be used with setuptools/distribute scripts on Windows, as spawned processes re-execute the original script.

[Tarek Ziadé]

Generated scripts now wraps their call in a main section. Fixes #11
