I agree. Utilities are inadequate for user interaction. Views should be 
used instead.

We don't need the request for managing TALES expressions inside an 
utility. The request is only needed if we *use* the expressions, and 
that should be done in view code, not in utilities.

Several tool methods have to be replaced by view code before we can 
register all tools as utilities.

The setup tool is responsible for managing configuration data. I can't 
see a need to care about the request in that context.
