Subject: [PATCH] fix ros::master::getTopics() getting worng results

The declaration of ros::master::getTopic says that each item in the result of ros::master::getTopics  should be a pair <string topic, string type>, but in the implement the item is a pair of <string topic, string uri> which is conflict with declaration.
