[mod_python] multi-line headers in multipart/form-data

I found that some http clients (Opera on windows, specifically in my
tests) use multi-line headers in some mime-parts... the same way email
clients do (with whitespace leading the continued lines). mod_python's
util.py appears to not support this.

Here's my quick patch to hack around the problem for me, if anyone
else is using multipart/form-data forms.

Or maybe someone has a better hack...
