Merge "Update WebView.loadDataWithBaseURL documentation."

     * <p>

     * If the base URL uses the data scheme, this method is equivalent to

     * calling {@link #loadData(String,String,String) loadData()} and the

     * historyUrl is ignored.

     * historyUrl is ignored, and the data will be treated as part of a data: URL.

     * If the base URL uses any other scheme, then the data will be loaded into

     * the WebView as a plain string (i.e. not part of a data URL) and any URL-encoded

     * entities in the string will not be decoded.

     *

     * @param baseUrl the URL to use as the page's base URL. If null defaults to

     *                'about:blank'.
