auto-save with merge versions

3.9: news.adde/camelot's implicit save command:
. camelot uses pyqt, activeMQ, Elixir (interfacing SQLalchemy),
to build apps faster by adding gui info to the model
like django admin interface does .
. they removed the save button 2 years before apple did
and explain this in their faq:
. if you don't like it, take a week off to get used to it .
. when the user asks for the save command
it should explain that it is already auto-saving versions,
and that when you hit save(merge versions),
that is deleting the old versions
(undoable until closing session).
