Fix topics/show page so that it reloads all comments via add_comment_to_all action in api controller, which points back to the api/comment partial in json.erb file. Add options to reinstallBehavior in base.js so that the UpdateTopic method can pass the new /api/add_comment_to_all url. And removed conflicting reinstallBehavior method from PreviewComment function in base.js since it was running renstallBehavior to early.
