turtlesim should use geometry_msgs/Twist and /cmd_vel

[chadrockey]

In this tutorial:
http://www.ros.org/wiki/ROS/Tutorials/UnderstandingTopics

We seem to suggest that robots should implement their own command message (turtlesim/Velocity). That's not correct, so we should show have turtlesim use /cmd_vel topics and geometry_msgs/Twist as is truly standard. Users often start their own software based on tutorials, so we need to make sure the tutorials follow standard practices.

Either someone provides a complete patch to modify the code and the wiki accordingly or we should just add a note stating that to the existing tutorial.

Change pushed.

The patch has been merged. The Wiki page must be updated but only after a new release is in the public repo.

For hydro right? We don't want to risk that someone out there probably
depends on that message for their robot.... >:(
