      - MultiMapping objects implement the has_key and get methods as
        defined for Python 1.5 dictionaries.

        methods of data-less C mix-in classes, C-based __call_method__
        hooks were broken.  The most notable example of this was the
        breaking of the Synchronized class.

      - Calling C-base-class special methods from overriding methods,
        as in::

          class LowerMultiMapping(MultiMapping):

	    def __getitem__(self, key):
	      return MultiMapping.__getitem__(self, lower(key))

        caused infinite loops.

calls on wrapped mapping objects to fail.

Added __bobo_debug_mode__ special module variable. When set it shows tracebacks,and tells you why it can't publish an object (i.e. not found, no doc string, unauthorized--no headers, or bad username/password, or starts with an underscore). Also special variables can be set through the environment BOBO_DEBUG_MODE, BOBO_HIDE_TRACEBACKS, BOBO_REALM. Note: __bobo_debug_mode__ overrides __bobo_hide_tracebacks__ which is now deprecated.

PATH_INFO.

Moved initial bobo_traverse before first use of top-level object.

pople who expect the base to be automatically interpolated. Also removed
extra blank lines written between headers and body, writing the headers
already adds \n\n.
