Camera and new view mode

The camera should only be accessible through commands. After placing and right-clicking the camera, the player assigns a camera to himself. By pressing F5 with the assigned camera we get a new view mode from the camera position. The camera does not move, so we can see one scene all the time and what is happening on it, no matter what the player does. Using the /summon command, we can bring up the camera with the lens directed exactly where the player is looking. This would be very helpful for many community contributors.
