Return all the names of Scenes in the AssetBundle.
                The names are the project-relative path of each .unity file, unless a different name was specified at build time.
                An AssetBundle can store either Scenes or Assets, never a mix of the two.  If the AssetBundle contains only Assets this returns an empty string array.
