[Zope-CMF] DCWorkflow version 0.4

[Shane Hathaway]

I've just posted version 0.4 of DCWorkflow.

With help from Ulrich, the implementation of workflow variables is now 
complete.  You can set up variable expressions on transitions and 
variable values on states.  Variables give you a *lot* of flexibility in 
workflows; try them out!

It is now required that you have the PageTemplates product installed. 
Expressions are now implemented with TALES!  This means we are now 
leveraging a carefully designed and documented expression engine, rather 
than the degenerate Python of DTML expressions.  It does mean you have 
to update all your expressions, but I think you'll find it's worth the 
gain in clarity.

I've also added an implementation of the "classic" workflow.  This means 
you can now simply drop in a DCWorkflow instance and almost precisely 
retain the old functionality.

Thanks to everyone for trying out DCWorkflow and contributing feedback. 
  Documentation will come in time. ;-)
