Sync Launchpad download files with PyPI

[sgt101]

Divisi source releases are done semi-automatically and hosted on PyPI (http://pypi.python.org/pypi/Divisi/0.6.10). But Launchpad doesn't reflect this: it doesn't point to the PyPI site, and instead has its own download section, which currently hosts old files.

We could manually upload new releases to Launchpad also, but that would easily get forgotten in the release process, so it should be automated. Launchpad has an API, so this should be not too hard, and someone may have done it already.

[original bug report by sgt101:
6.8 is available as a windows exec - is it possible for you to tar up a 6.8 (or 6.10???) so that I can install it and run luminoso on my mac?]
