Subscribe feature

[gordonpn]

As a user, I want a subscription form, so that I can subscribe to the newsletter.

Acceptance criteria

• When a user subscribes through the site, an email should be dispatched to that email
• Captcha to submit
• The page changes to tell the user that an email has been sent and that they need to confirm
• The form only takes a name and an email (do proper sanitizing and validation!)
• A row is added to the database with confirmed set to false and an email md5 hash (need to add these columns)
