adding titles and summaries to social media share links

I added parameters into the links instead of using Open Graph tags (og tags) as discussed with Dak. OG tags give us more control over what displays when shared, especially in Twitter. But, this is still a big improvement over what we have now.
Summary and title shouldn't update in every single view, but url should update. for example, if I am in College Physics and click the next link, og:title and og:description should not update, but og:url should.
