Title: change view helpfulness

create ContributorsPage with . click_top_visited_article_link(),
.click_this_week(), and .click_all_time()
add SupportHomePage.click_knowledge_base_dashboard_link()
add KnowledgeBaseArticle.vote_helpful(), .vote_not_helpful(),
.can_vote(), .vote()
modify test_view_helpfulness_chart.py to use above

locators based on link text should be replaced when and if developers
put ids on these items.
