Make 'forbiddenre' significantly more powerful by allowing folks to

distinguish between file and directory paths.

* viewvc.conf.dist
  (forbiddenre): Update documentation to note that directory paths
    will contains trailing slashes, and provide a related example.

* lib/config.py
  (is_forbidden): If using the 'forbiddenre' option, test directory
    paths only after appending a trailing forward slash.
