Drastically simplified the connection between QObject properties and the settings. Thus the UiGuiSettingsDialog widgets do no longer need to have a special object name. Instead they need custom properties "connectedPropertyName" and "connectedSettingName" set, which then can be used to create the connection to the setting.
