- Divided ImGui settings into UImGuiSettings persistent object and FImGuiModuleSettings proxy that provides interface for other classes and handles delayed loading of UImGuiSettings. - Removed from FImGuiModuleProperties and FImGuiModuleCommands direct dependencies on UImGuiSettings. - Simplified FImGuiModuleProperties making it more robust when moving data after hot-reloading. - Inverted binding logic by injecting FImGuiModuleProperties and FImGuiModuleCommands into FImGuiModuleSettings and letting it take care of synchronization. Dependencies are setup by module manager. - Added to module manager FImGuiModuleSettings and interface to access it. - Cleaned interface of FImGuiInputHandlerFactory and removed direct dependency on settings.
