Update documentation for deployment with mod_wsgi
add #125 and #129 to troubleshooting
import backports.configparser before configparser, #128

backports.configparser got a major rewrite and an upgrade from 3.3 to
3.5 imports the wrong configparser module on Python 2.6/2.7.

Hopefully, this commit makes it work again. Alternatively, you can
remove the old configparser module(s):

  rm lib/python2.7/site-packages/configparser*

And re-install configparser from PyPi.
