Don't log failure to load the extension during initialization, because it isn't needed for many uses of wxWebView. Instead, only report the failure at the time when functionality depending on it is used. Also use g_warning() for logging consistently with other failures in this file. This doesn't interrupt the user, yet shows the problem highly visibly in the console.
