I find this instance of manager.register, as well as [the one in PublishManager.publish](https://github.com/RobotWebTools/rosbridge_suite/pull/79/files#diff-5de390a84a194f6692ef968c0c177283R340) redundant. From what I can see, doing just "(new ROSLIB.Topic()).publish()" ends up with three separate calls to manager.register().

I added the latch parameter to all three for consistency although at some point it might be better to understand this redundancy in manager.register() calls and remove it if possible.
