We need new collections: /events/42/comments/reported (event comments) and events/42/talk_comments/reported (talk comments). These should return a collection of resources from the (mysql table) reported_event_comments and reported_talk_comments tables.
Each Event resource should contain a link to the individual record of this report, and the fields from the reported_*_comments table. It should also have the related comment itself as a nested resource.
These endpoints should only be available to the event admins for this event, and to site admins. Links to these endpoints should be included in the verbose version of then event resource.
