[mod_python] Module importer issues list updated.

In preparation of mod_python 3.2.X (final) being not too far away, I
have updated my article on module importer issues in mod_python with
references to changes in 3.2. The two articles related to the module
importer, the first being background and the second being the list of
issues, can be found at:
