ALTER TABLE {$NAMESPACE}_ponder.ponder_answer
  ADD UNIQUE KEY `key_oneanswerperquestion` (questionID, authorPHID);
Require answers' authors to be unique in Ponder Summary: Ref T3578. I forget if this was an explicit decision or not, but we currently let the same user answer questions multiple times. I think this probably causes more confusion than it provides freedom. In conjunction with other UI issues (commenting being weird, notably), we're seeing some use of answers to comment, which is undesirable. Require each answer's author to be unique. Merge existing nonunique authors' answers.
