UX: Prefab Family Popup terminology needs to be improved.

Prefab Family Popup:

"This Prefab doesn't have any children.

Prefab Variants created from this Prefab will be listed here."

->

Prefab Variants created from this Prefab will be listed here."

 

Also add a text if no Variant ancestors exists.
