[Snowy] Guide for using Snowy with Apache and mod_python

[Sandy Armstrong <sanfordarmstrong gmail com>]

Hey folks,

I've updated Piotr Gaczkowski's guide to deploying Snowy on Apache/mod_python:

http://live.gnome.org/Snowy/ModPython

Again, these fixes are mostly from jmullan in IRC, so thanks again.

I've only tested these instructions with localhost access, so if you
try it out and notice any gotchas, feel free to update the page or
ping me.

Sandy
