Merge pull request #3 from dbnicholson/master

Support backuping up API data
Merge pull request #4 from dbnicholson/master

Only add Teams repo for own repositories
Don't download pull patches

These aren't served over the API, so they can only be downloaded when
logged in. That's OK for our use case since pulls always come from a
branch in our own repo and the commits will be present in the repo
itself. The information for where to see the pull request is available
in the json.
