Subject: Add GameLoader Autoload to handle global loading data Remove
 GameDebug, Localization, and ShaderManager from Events.gd Renamed
 OptionsSingleton class_name to OptionsEventsObject Add Events.Loader to
 handle Loader events (which are global signals) Make GameDebug singleton with
 static functions and property Make Localization functions static Move
 ShaderManager variable to GameLoader Move Events._define_filepaths_dict to
 GameLoader.define_filepaths_dict Move game initialization from
 LoadingScreen.gd and Events.gd to GameStart.gd Attach GameStart.gd to
 GameStart.tscn root Make LoadingScreen generalized and so it is reusable
 Remove class_name from LoaderingScreen.gd
