svnmeta: store youngest revision pulled from subversion This prevents re-pulling the same revision over and over, which was a problem when the most recent revision was a tagging revision that wouldn't exist properly in the revmap. This should also allow users to not re-pull huge volumes of commits that have no effect on the hg repository.
