Create a "Previous production deployments" section

When you do a new production release, it bumps the previous production release down to the Preview Deployments section. It would be useful instead to have another table/section specifically for previous production deployments. This would give a chronological history of your deployments. Only deployments which were live in production would appear here. It might contain the following information:

* Committer
* Commit message
* Branch name
* Commit hash
* Start date (date and time deploy became live)
* End date (date and time deploy became inactive)
* Live duration
* 'Redeploy' button to promote back to live

Inclusion of a free-text filter would be grand too. Deployments which were redeployed would appear more than once in the table (one entry per live-in-production period).
