Project downloads aren't migrated to GitHub

[GoogleCodeExporter]

Hi there,

I'm migrating our old support projects for Summer of Code to GitHub and have 
noticed that the downloads aren't being moved across. Arbitrary blobs are being 
retained if they're attached to issues, so our GHOP repo is intact ( 
https://github.com/MatthewWilkes/google-highly-open-participation-plone )

Downloads, however, aren't being added as releases, as I'd expect. For example:

https://code.google.com/p/google-summer-of-code-2008-plone/downloads/list
https://github.com/MatthewWilkes/google-summer-of-code-2008-plone

Can we get an update to the migrator to handle these old OSPO repositories 
correctly?

Cheers,

Matt Wilkes
