Enhance the SmartDriverUtil to include a findAncestor

[chrisdavis83]

Considering the following method:

/**
 *
 * Finds the webfriend of a child elements parent
 *
 * @param driver the web driver
 * @param childElement the child web element
 * @param elementTag the element tag to wrap element with
 * @param <T> the web friends element type returned
 * @param <I> the web friends element type input
 * @return
 */
public static <T extends SElement, I extends SElement> T findWebFriendParent(final SmartDriver driver, final I childElement, final TagTypeSelenium<T> elementTag) {
	return findWebFriendParent(driver, childElement.getWebElement(), elementTag);
}

Could we add to it where it iterates up through the html tree looking for an ancestor which matches a webfriends element type
