We're writing lots of tutorials and trying to orient them around teaching people
modern ways to do things in NetBeans.  But in some cases, there are support
classes for things we *don't* want people to do, and none for the thing we *do*
want them to do.

CookieAction is a case in point - I want to teach people how to use Lookup
effectively, and not tell anyone to subclass Node.Cookie.  But if I do that,
then they need to implement ContextAwareAction themselves - which is really
implementing plumbing we already have for CookieAction - we just need an
equivalent that works against Utilities.actionsGlobalContext().
