Subject: [PATCH] Added IRegionCreator interface that all ApplicationPlugins
 that are creators of Scenes should implement and register with the
 ApplicationRegistry.StackModuleInterface<>(); So that other plugins can
 attach to their OnNewRegionCreated event. Made some changes to IRegistryCore
 and RegistryCore so they support "Stacked" interfaces.
