/**
 * URLNavigator
 *
 * The URLNavigator class extends the Flash built-in method, navigateToURL.
 * This class copies the Firefox browser's link-click action.
 * If you click on a link with the "Ctrl" key held down, the link will be opened in a new window or a new tab, depend on the browser's settings.
 * Or Flash Player tries to download the url, if the "Alt" key is held down.
