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.
This doesn't change the fact that `@addOpenGraphMetaTags()` will still be called 100% of the time for every single view.  Every single view calls `render`, which then calls `updatePageInfo`, which will always call `@addOpenGraphMetaTags()`.
