The CMFActionIcons tool tries to organized "equivalent" actions based on 
category:  if two providers (e.g., Document and File TypeInformation in 
the portal_types tool) both supply an action whose category is 'object' 
and whose id is 'edit', the tool assigns them both the same icon.  This 
is by design:  keeping the same icons for actions which are logically 
"alike" gives the user more ability to grasp their meaning.

If two unrelated providers each supply actions whose IDs and categories 
clash, but which shouldn't be treated as equivalent by the tool, then 
the tool expects the site manager to rename either the ID or the 
category for one of the actions.

I could imagine extending the tool to support such extra metadata about 
actions (we thought had a use for per-action javascript snippets at one 
point).  Dieter Maurer is supplying an slternative patch, which would 
allow decorating actions on individual providers with arbitrary extra
