Bug 18397: Add message delivery details to the notices tab

This patch adds further delivery details to the notices tab in patron
details in the staff client.

Once a message is sent, we display the 'from:', 'to:' and 'cc:'
addresses in the 'Delivery note' column when they exist.

Test plan
1. Enable KTD to send email [1] (without email configured the
   delivery note displayed "Unhandled email failure, check the logs for
   further details").

2. Add email addresses to two patrons and to KohaAdminEmailAddress,
   and run misc/cronjobs/process_message_queue.pl after generating
   notices.

3. For the two patrons with email addresses, make one a guarantor.

4. Sent Welcome messages (Patron account > More > Send welcome email) -
   nothing in delivery note column.

5. Checkout out an item to the guarantee (item checkout email enabled) -
   nothing in delivery note column.

6. Send the notices by running misc/cronjobs/process_message_queue.pl
   again.

7. Now the 'Delivery note' columns should contain from:, to: and cc:
   address details.

[1] Option 1 - smpt-sink (aka the sandboxes way)
    - Install the postfix package inside ktd (sudo apt install postfix)
      When asked in the wizard, I named mine 'local'
    - Start smpt-sink with
      `nohup smtp-sink -u root -D mail 127.0.0.1:25 100 </dev/null >/dev/null 2>&1 &`

    Option 2 - To test sending emails using a Google account:
    - Set up an App password for your Google Account
    - Edit /etc/koha/sites/kohadev/koha-conf.xml file and add this
      configuration near the end (where <user_name> = your Google email
      address; <password> = your APP password, not your Google account
      password):

      <smtp_server>
        <host>smtp.gmail.com</host>
        <port>587</port>
        <timeout>5</timeout>
        <ssl_mode>STARTTLS</ssl_mode>
        <user_name>GOOGLEACCOUNTUSER</user_name>
        <password>GOOGLEAPPPASSWORD</password>
        <debug>1</debug>
      </smtp_server>
