Wrong visual about PointStamped radius

[Julien-Livet]

I observed a vocabulary mistake about PointStamped display : the field "Radius" currently matches to the diameter (with TF display).
I think it is more simple to rename the field than correct the code (div by 2), probably https://github.com/ros-visualization/rviz/blob/5531206e77d8092dbdb6a50a5b1a3c23fe5e181e/src/rviz/default_plugin/point_display.cpp or here https://github.com/ros-visualization/rviz/blob/5531206e77d8092dbdb6a50a5b1a3c23fe5e181e/src/rviz/default_plugin/point_visual.cpp.
