Provides and controls the active level for activeBuilding. Will be updated whenever
activeBuilding changes, and may be set to any member of activeBuilding’s levels property. May
also be set to nil if the building is underground, to stop showing the building (the building
will remain active).
Will always be nil if activeBuilding is nil.
Any attempt to set it to an invalid value will be ignored.
