I added some server-side logging during the research hackathon last weekend, and I'd like to solicit feedback.

The patch will record all attempts to save through EditPage or ApiEditPage, whether or not they are successful.

Would it make sense to log further down, like in doEditContent?  Should we also write a log at the beginning of each edit session, to track dropout?
