Summary: Adds a very basic list of all inline comments, threaded, and their status. Kept this a little simpler than the mock, mostly because sorting here feels a little strange given threads would be all over the place. Not sure sorted is needed in practice anyways. I'd probably lean towards just adding a JS checkbox to hide certain rows if needed in the future. Test Plan: Test various commenting structures: - Leave Comment - Update Diff - Leave new comment - Reply to comment - Reply to comment as revision author - Mark items as done - Update diff again {F4996915} Reviewers: epriestley Reviewed By: epriestley Subscribers: Korvin, epriestley Differential Revision: https://secure.phabricator.com/D18112
