Initial RNA for scene layers
Next will be the collections, and then the other missing props of rna_def_scene_layer
Note: it would be nice to have a way to tag rna properties asa
deprecated. For example, scene.engine can still be valid (and mapped to
scene.layers.active.engine), but it would be nice to indicate the addon
writers of the new API.
