Revert to free-look during periods of zoom-in and zoom-out modes

[Edward Hart-Davis]

Because it's confusing to the user to be unable to move the camera to look around while not inside the sphere, and approaching it, or leaving it.

This is done when the player dies, but the camera is locked again when zooming in, to show the titles, if and only if the player has their camera mode set to lock - this seems a good compromise.
