Update 4.3.1

• Added config_default.json file where new configurable game options will now be added. New configuration settings will no longer overwrite the file (config.json) with your settings. Attention: the game parses the config.json file at startup. To add new options, you should copy them from the config_default.json file.

• Added a new customization option to remove FPS lock.
