Find out who gave in Bloomerang after a Mailchimp appeal

**Objective:** Measure the giving that followed the Mailchimp campaign `{campaign}` (a title or campaign id): which recipients gave in Bloomerang within `{days-after}` days (default 30) of the send date, split by whether they opened or clicked.

**Step 1: Find the campaign**

Call `mailchimp-get-campaign` with `campaign-id`, or with `title.contains` if `{campaign}` is not an id. If more than one matches, list them (title, send-date, status) and stop. If it has not been sent, say so and stop. Note campaign-id and send-date.

**Step 2: Read the recipients**

Call `mailchimp-get-campaign-recipient` with `campaign-id`, keeping email-address, status and open-count. Then call `mailchimp-get-campaign-email-activity` with `campaign-id` and `action` set to click to learn who clicked.

**Step 3: Match recipients to Bloomerang**

For each recipient call `bloomerang-get-email-address` with `value` set to their email-address to get the `account-id`. If nothing comes back, count the recipient as not in Bloomerang and continue.

**Step 4: Read their gifts**

For each matched account-id call `bloomerang-get-transaction` with `account-id`, `date.from` set to the send date and `date.to` set to the send date plus the window. Ignore refunded transactions.

**Step 5: Report**

A summary of recipients, matched to Bloomerang, donors and total given, broken down by clicked, opened but did not click, and did not open. Then a table of each donor: name, email, engagement (clicked/opened/none), gift date and amount. Note the campaign's own open-rate and click-rate from `mailchimp-get-report` for context.

**Rules & Guidelines:**

* Tools starting mailchimp- are on the mailchimp server; tools starting bloomerang- are on the bloomerang server.
* Read-only. Do NOT call `mailchimp-replicate-campaign`, `bloomerang-add-interaction` or `bloomerang-add-transaction`.
* Say that a gift after an email is correlation, not proof the email caused it.

**Validation:**

* If no recipients match Bloomerang, say so and report the match rate.
* Match emails case-insensitively.
* If a recipient's email maps to more than one account-id, list them and do not double count the gift.
