Unsubscribe feature

[gordonpn]

As a user, I want a link to unsubscribe, so that I can unsubscribe if ever I am not interested anymore.

Acceptance criteria

• Every newsletter should include a link to unsubscribe in the footer
• The link would look something like https://deals.gordon-pn.com/unsubscribe/aebafcacecf7fa16a68f6b26b0abfcee (or use parameters)
• When clicked, search the database for the same hash and remove the row (1 click unsubscribe)
• Show a page with success then return to main page after timeout
• If not found, just return success to the user (prevent unethical users)
