Update Blog Layout

Summary:
Updated the blog's styling to make it more readable.

* BlogPageLayout (blog index) - Only excerpts from each article are now shown, as opposed to the entire article.
* BlogPost - Broken up into headers, footers. Reorder header so that the blog post title is closer to the content. Adds support for hero images (visible from the blog index). Adds Facebook, Twitter social share buttons. List items are properly spaced now.

Blog index:

 React Native's goal is to give you the best possible developer experience. A big part of it is the time it takes between you save a file and be able to see the changes. Our goal is to get this feedback loop to be under 1 second, even as your app grows.

 Part of having a great developer experience is having great documentation. A lot goes into creating good docs - the ideal documentation is concise, helpful, accurate, complete, and delightful. Recently we've been working hard to make the docs better based on your feedback, and we wanted to share some of the improvements we've made.

 Last week I had the opportunity to attend the [React Native Meetup](http://www.meetup.com/React-Native-San-Francisco/photos/27168649/#452793854) at Zynga’s San Francisco office. With around 200 people in attendance, it served as a great place to meet other developers near me that are also interested in React Native.
 
 I was particularly interested in learning more about how React and React Native are used at companies like Zynga, Netflix, and Airbnb. The agenda for the night would be as follows:
