Support "back" and "forward" navigation action #164
Description
Context: a task requires navigating back to the previous page. e.g., webwand clicks one of the result from the search result, and realizes that this result is not the right option. So it should go back to the search result to check another result.
Status quo: right now webwand does not support “backward“ action. So it has to open a new website, type the search query again to enter the search result page.
Expected: webwand should be able to perform “backward“ and “forwards“ browser navigation.
