[Seaside] Implement "please wait" message using smallfaces.

[Timothy James Ziebart]

Ok now I know why it's doing it.  I have a collection of panes I need to 
be refreshed (when: send: to: refresh:) and the message will be 
refreshed during the processing of the collection.  What I need it to do is:

1. update the message to working status
2. on success refresh the remaining panes
3. when the panes are all refreshed (including the hit list)
4. update the message to a ready status.

Hmmm can this be done in SmallFaces using (when:send:to:refresh:)?  Or 
do I just evaluate javascript (when: evaluateJavascript:)?
