Config names are forced to lowercase even when json files are saved without forced lowercase

[NanobotZ]

Configs cause confusion due to current case handling.
Reloading configs forces their names to lowercase.

Example:
Create config ModLoaderConfig.create_config("MyMod", "MyConfig", {}.
Config gets saved as MyConfig.json.
ModLoader reloads configs.
Calling ModLoaderConfig.get_configs("MyMod") reveals a default and myconfig configs, and ModLoaderConfig.get_config("MyMod", "MyConfig") returns null.
