og:site_name support

[ummjackson]

Hi there, thanks for building this - it's very handy and works great! I was hoping you might be interested in adding the og:site_name variable to fetch the Site Name tag if present? Most big websites include this and it'd be very helpful to have.

If you'd prefer I go ahead and work on a Pull Request just let me know, but figured as maintainer you're most familiar with how this could quickly be added.
