[Squeakland] publish proj - save change set

[Randy Heiland]

It seems that a relatively new prompt that now occurs (perhaps in the  
post-Squeakfest version) is when I Publish a project and am always  
prompted:
"would you like to include all the changes in the change set as part  
of this publishing operation"

Why is this now there?  What happens if I answer yes/no?  Can I make  
it default to the "safe" answer?

thanks, Randy
