[mod_python] Apache directory listing

BTW, SetHandler is only processed in typehandler phase. Thus if you
want to override that, you must be doing it in the fixuphandler phase.

Also note that allowing automatic directory listings in mod_python can
cause issues if there are subdirectories which are also managed in
some way by mod_python. Can't remember whether there is an issue
logged about it or whether I ranted about it on one of the mailing
lists somewhere.
