Prepare 0.2.0 release

In this second release we **added support** to:
- Export AMP along with required libraries for AMP rendering
- Configure custom HTML and AMP element exporters
- Resolve oembed elements in HTML export

One potentially **breaking change** was added:
- Export quotes as `<div>` instead of `<aside>`

**Fixes**:
- Support Vimeo videos with old flash player URLs
- Make Google Parser more fault tolerant
- Respect linebreaks when importing Google Docs
- Export linebreaks in JSON to `<br>` tags in HTML / AMP

Also add @towanda and myself as gem authors to the gemspec and change
authors to contain clear names instead of Github handle (since this is
the community standard)
