darcs patch: Placeholder for a manual section on image persistence

[Brian Rice]

I have filled in this section with notes on image saving and startup  
and related hooks. I have also added saveActions and handleSave for  
pre-save hooks that may be needed in the future to clear out  
information that the user does not want stored on disk - for example,  
passwords.
