#161 Provide a NoRefreshHandler

[Cimballi]

Something like this for the ones who don't want the page to be refreshed.

/*
/
public class NoRefreshHandler implements RefreshHandler {

/**
 */
public NoRefreshHandler() {
    super();
}

/**
 * @see com.gargoylesoftware.htmlunit.RefreshHandler#handleRefresh(com.gargoylesoftware.htmlunit.Page,
 * java.net.URL, int)
 */
@Override
public void handleRefresh(final Page arg0, final URL arg1, final int arg2)
throws IOException {
    // Nothing to do.
}

}
