Certificate Detail, clicking on (Private) Key dismisses and navigates to Private Keys tab

[kzurell]

Recently compiled several CAs with numerous certs in a database.

Had to search by internal name for private keys, with several having similar names by accident of our specification.

It would be useful to double-click on the Key field of cert. details (or a button), and, rather than showing the key details dialog, dismiss the cert. detail, navigate to the Private Key tab, and select the key (for export to clipboard and so on.)
