- Make environment variable settings case InSenSiTive: INVOKEAI_MAX_LOADED_MODELS and InvokeAI_Max_Loaded_Models environment variables will both set `max_loaded_models` - Updated realesrgan to use new config system. - Updated textual_inversion_training to use new config system. - Discovered a race condition when InvokeAIAppConfig is created at module load time, which makes it impossible to customize or replace the help message produced with --help on the command line. To fix this, moved all instances of get_invokeai_config() from module load time to object initialization time. Makes code cleaner, too. - Added `--from_file` argument to `invokeai-node-cli` and changed github action to match. CI tests will hopefully work now.
