enable to jsk_rviz_plugins, without rviz/ogre

[k-okada]

use jsk_rviz_plugins message within embedded environment, compile with
catkin bt -vi --cmake-args -DUSE_VISUALIZATION=OFF

A jsk_rviz_plugins_msgs would be helpful too, I'd like to be able to publish OverlayText and similar from an embedded system but not have to build anything that depends on rviz. But it would also require a bunch of code importing those messages to be changed to the new package name.
