Auto update all forks

[rajbos]

All forks are already out of date. We should update them automatically :-D.

Not sure how this will work with the repos that have strange fork networks. It might be better to convert all of this to mirror the repos, since that will give less confusion.

Then we can prefix the mirror with owner@ so it will become recognizable: owner@reponame so we always know where this is coming from.
