- Speed up ``repoze.bfg.traversal.model_path``.

- Speed up ``repoze.bfg.traversal.model_path_tuple`` slightly.

- Speed up ``repoze.bfg.traversal.traverse`` slightly.

- In 0.8a7, the return value expected from an object implementing
  ``ITraverserFactory`` was changed from a sequence of values to a
  dictionary containing the keys ``context``, ``view_name``,
  ``subpath``, ``traversed``, ``virtual_root``, ``virtual_root_path``,
  and ``root``.  Until now, old-style traversers which returned a
  sequence have continued to work but have generated a deprecation
  warning.  In this release, traversers which return a sequence
  instead of a dictionary will no longer work.
