Subject: [PATCH] enable using announcements to add content to alerts

If an announcement has a location of 'alerts' then include that at the
top of all alerts. The HTML version either uses "Read more" or the
`button_text` property for the link.

Announcements are added at the top of the alerts.

Part of #1825
