Unfortunately these files conflicted with the ones in Clouseau, so that means at 
some point I'm going to have to factor these out into a common library. In the
meantime, I quickly renamed all the files to be unique, thats rename.py.

Plone already has CSS to highlight comment fields, which meant that comments come
out all wonky. So replace.py runs through and changes all comment fields. I probably
messed up some JS at some point by doing this.
