Changed "isRunningInWrapperApp" to "isRunningInMobileApp".
Fixed "\n" character in the "failed to load page" message.
Made the app open URLs that match configured navigationItems in the wrapper app (MENU-1360).

When the wrapper app receives a request to navigate to a URL, it normally just opens Safari.  But if it receives a URL that matches a configured navigation/menu item, it will open the web view for that instead.
