        ** See bugs #52061 & #52669.

        * gui/smime-ui.glade: added cert-trust-dialog and tweaked the
        ca-trust-dialog.

        * gui/ca-trust-dialog.c (ca_trust_dialog_show): Fix the %s in the
        label.  Slack.
        (ca_trust_dialog_show): slight rearrangement.

        * gui/certificate-manager.c (add_contact_cert): fill out fields.

        * lib/e-cert.c (e_cert_get_usage): helper to get the usage of a
        cert.

        * gui/certificate-manager.c (edit_ca): use the right certdb, not
        the e-one.
        (add_user_cert): fill out missing columns.

        * lib/e-cert.c (e_cert_get_ca_cert): new method to find the ca
        cert of a cert.

        * gui/cert-trust-dialog.[ch]: peer cert trust editor.

        * gui/certificate-manager.c (edit_contact): implement.
