As a campaigner, I want all emails to have unique URLs so that I can track who clicked what

[camjackson]

Each email sent to each member should contain unique URLs, for analytics purposes. We want to know who clicked on what link, in which email.

Proposed solution is that whenever the mailer sends emails, it pre-processes the email body, replacing any links in the email with special unique ones for each member. The URLs:

• should point to the Rabble Rouser redirector
• should contain the original URL, so the redirector knows where to send people
• should contain the member ID, so we know who clicked the link
• should contain the email ID, so we know which email they clicked it in

The redirector will then redirect the user to the original URL, and record an event that says that the user clicked on the link (out of scope, done in a separate task from this one).

@tomsulston, @akjones, @pameck, would appreciate your thoughts on this. Does it sound correct that the mailer just magically replaces all URLs with unique ones that point to the redirector?

I think Bal (don't have his github handle) has started work on this already. Not sure how far he has gotten.
