Add Open Graph meta tags for facebook sharing

[ChristianVermeulen]

When sharing an event / dojo on Facebook there is nothing in the preview. Not even a proper title or description 😢.

Could we at least at:

• og:title => CoderDojo {name} | Zen
• og:description => {EventName} at {coderdojoName} on {date}
• og:image => e.g. map preview with location marker or default image with register call to action

This would increase social engagement tremendously!
