This will allow users to reply to private messages even when they do not have the u_sendpm permission. The idea behind this is that when a user sends another user a message, they are going to expect a response, and therefore implicitly allowing the user to reply.

So we achieve this by removing the permission check when replying. Of course thinking about it now, users can still abuse this if they are originally allowed to send messages and then lose their permission but because of this change may still reply to existing messages. Perhaps a new permission will be necessary (e.g. u_noreply) to make sure users cannot reply to any private messages?
