Review Request #4076 — Created April 23, 2013 and submitted
Enable logging of request info for Review Board. This improves Review Board's logging to use Djblets's new request logging code. This will log the localsite name (if any), the username, and the path of the request.
Unit tests pass. Ran pyflakes to make sure we weren't accessing any invalid 'request' variables. Played around with various pages that log data. Didn't see any problems.
