Streamlining Script

I’ve got a heap of stuff in the toolbox script that does nothing anymore - at least on my site - so I think I might streamline it a bit by removing a large number of the functions that are no longer required. For instance, I don’t need to create Gravatars in JavaScript, since there’s a Smarty Plugin to do this - which also negates the need for the md5 stuff. At the moment, the script is 56k, which is a little too bulky.
