I have added/modified two methods to make the Workspace text persistent. 
'accept' writes the text to a Text file, default name is the name of the 
window. 'cancel' reads a corresponding file.

Now a question before I publish this very small small goodie:
    I have used '.ws' as file extension. Does that conflict with anything else?
    If so, what should I use?

Regards

P.S. I use persistent workspaces as notebooks/logs so that I remember how 
to recreate my working image from scratch.
