Enable resend for lost messages

Description

In a distributed configuration it can happen that Backbone messages get lost - they might get deleted on the file system or lost in an email which does not arrive.
When a message got lost, the next message complains in the troubleshooting that a previous message is not yet processed.

Improvement
Backbone could archive all the messages it sends and delete the archived copy only after it received the confirmation that it has been processed.
If a message gets lost now, the user could request a resend of the message in the troubleshooting.
