Summary:
We had rendering support for prev links, but we never had any previous links in our metadata. Only next links. This adds that support to both Guides and APIs.
**For guides**: `previous` is manually inserted into the metadata of the actual markdown file.
**For APIs/Components**: `previous` is established via code within `extractDocs.js`
> This isn't totally perfect. For example, the transition from the last guide to the first API/component has a next link from the guide, but not a previous link from the API since the way you get the previous links are different from guides and APIs. But this gets us really close.

This is in preparation for open sourcing React Native for Android.
Also add hyphens to URLs for consistency. This can break people's
browser bookmarks but it's better to be consistent and we can
redirect to docs: https://github.com/facebook/react-native/issues/2137
Test plan: Ran the website locally using `cd website; npm start`
and checked all pages render correctly.

"Testing" separately.
