changelog
Fairer ordering of requests when backing up many repositories at once.

Before, the first repository could use up all the API each time a backup
was run, and the rest would starve. Now, failed requests are run first
across the repos.
Avoid making requests for data that has already been backed up before until after new data has been backed up.
