1. The invokeai-configure script has now been refactored. The work of selecting and downloading initial models at install time is now done by a script named invokeai-initial-models (module name is ldm.invoke.config.initial_model_select) The calling arguments for invokeai-configure have not changed, so nothing should break. After initializing the root directory, the script calls invokeai-initial-models to let the user select the starting models to install. 2. invokeai-initial-models puts up a console GUI with checkboxes to indicate which models to install. It respects the --default_only and --yes arguments so that CI will continue to work. 3. User can now edit the VAE assigned to diffusers models in the CLI. 4. Fixed a bug that caused a crash during model loading when the VAE is set to None, rather than being empty.
