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.
