Preset operators should avoid using `bpy.context.object.data` as a base
path to properties. This path is not available in the buttons context
when using pinned datablocks! Instead use the specific
`bpy.context.camera` and `bpy.context.lamp.sky` paths now, which lead to
the correct datablocks in any case.

- Do not change save the distance factor since this is not relevant as a preset, it should stay at what ever the user
set it to work with that particular scene
- fixed a tooltip
