0.2.1

• Changes for standardizing access to settings. Now, BuildContext() extensions have limited options for accessing settings. The available context methods include setting<T>() and listenSetting<T>(). Additionally, the of() method has been deprecated in favor of two separate methods, from() and listenFrom().
• Now, to create settings, it is mandatory to create a class based on SettingsModel() for settings or a class based on ConfigModel() for configs. The type of this class must be specified when accessing settings through context methods.
• Thanks to standardization, ScenarioBuilder() can now be used in both configs and regular settings.
• A bug with local saving of Scenario properties has been fixed.
