Support Open Graph

Is meta-data to make links to the site look pretty on facebook.

Open Graph - http://ogp.me/ Current state of the site in OG - https://developers.facebook.com/tools/debug/og/object?q=history.newtheatre.org.uk

• [x] Generic content pages should have a generic image, title and excerpt
• [x] People should have title, headshot and excerpt. Need a placeholder headshot.
• [x] Shows should use their poster or equivalent.

Might be an idea to implement an attribute for all pages, display_image, or similar which is an image to represent the page (poster, headshot, generic etc)
