[mod_python] options to suppress error when accessing module directly with Publisher

I am. I'm sorry I didn't test it on my 3.1 installation, where it works 
as expected. I made a wrong assumption when I glanced at the current 
docs for info on Publisher traversal:

  http://www.modpython.org/live/current/doc-html/hand-pub-alg-trav.html

It turns out that this example refers to the module *and* function, 
which are both named index:

  http://www.somehost/index/ will return "We are in index()"

Thanks for pointing out the 3.1 behaviour.

True, but I'm revamping the site in preparation for upgrading to apache 
2.x/mod_python 3.x, where it won't be an issue.
