[mod_python] .value in FieldStorage

Markus -

The rationale is that not everyone using mod_python is migrating from CGI.
For those of us who are writing mod_python handlers from scratch having to
use .value all over the place seemed like an annoyance.

Rather than patching mod_python code, I suggest either subclassing
FieldStorage, or using cgi.FieldStorage.
