* Add an AboutUserID field to feedbacks, so when the report is about a picture that is later deleted, the feedback can still link to the original owner's account instead of showing an error. * Add filters to the User Notes page so the admin can see: * All feedback From or About the user or their content (default) * Feedback created by the user * Feedback about the user or their content * Fuzzy search for any feedback containing the user's name. * On chat room reports: make the @channel ID a clickable user profile link for convenience.
