Use origin/master instead of master as the basis for patches. I believe this is correct based on my understanding of how review board handles git repositories. That is to say, review board will try to apply the parent diff (or the review diff if a parent isn't provided) to origin/master, so we should be generating patches based on that. This allows us to create reviews based on a local master that has not been pushed up to origin.
