Webware for Python

Update of /cvsroot/webware/Webware/MiddleKit/Tests/MKRefresh.mkmodel
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv10534/Tests/MKRefresh.mkmodel

Added Files:
	Classes.csv Settings1.config TestEmpty.py 
Log Message:
Added assertion checks to detect when a changed object is about to be 
refreshed from the database (changes would be lost).  See release notes for 
details.

In order to detect this reliably I tweaked the logic in the generated code
which sets MiddleObject._mk_changed, so that it only gets set when an attribute 
actually changes.  Hopefully this doesn't break anyone's logic, but IMO the 
old semantics for this flag were pretty much useless, and this needs to be 
fixed at some point.
