Add script to publish all draft AAIB reports.

[Trello ticket](https://trello.com/c/G1SEv3PD/363-script-to-change-the-state-in-preview-for-aaib-reports-from-draft-to-published-1)

This script uses $stdout.flush and $stdout.sync = true liberally in
order to make sure the console output is legible and useful for whoever
in 2nd-line ends up running this script.

It takes around a second a time to run but is idempotent so can be run again and again.
