[Zope] long folder listing patch

I have been sitting at home with the flu, working on a laptop in bed, and I finally got sick of scrolling down the list of objects with my touchpad. Here is a patch that renders the folder list as a 2 column table, as well as puts a copy of the rename, copy, paste, etc buttons at the top as well as the bottom. The folder list only renders as a table if you create a boolean property for the folder called 'tableize' and set it to true. --sam
