rviz: camera visualization (ros-pkg ticket #998)

[hershwg]

2 broad ideas:

1. Project camera image into the world (onto anything that gets into its way, i.e. point clouds)
2. Pop up a panel with another render window -- render the camera image at some transparency, and render the scene from the POV of the camera

Leaning towards #2, mainly because #1 has a lot of problems associated with it (what if there's nothing in the world to project onto, how well it will actually work, etc.)
