* ID blocks can now get RNA properties defined from python, e.g.: bpy.types.Scene.BoolProperty(..) * RNA structs/functions/properties can now get pointers duplicated (mostly strings), since we can't point to some static string then. * Added ExtensionRNA struct to add into *Type structs for subclassing, is a bit more compact than defining the 4 variables each time. Only disadvantage is it requires including RNA in more places.
