From 54ffea24196e8f5d88cf9d8607455f0f6aab305c Mon Sep 17 00:00:00 2001
From: Tim Almdal <tnalmdal@shaw.ca>

Subject: Split the clean method into two clean and purify. clean is a light
 weight approach using html::specialchars and purify uses HTMLPurifier to
 intelligently cleanse the output fields. Use purifier for text and title
 fields where it is likely that a user would enter html to format their data.
