* Description:   Implementation of class CCertManUIContainerTrust.

*                Maintains correct list of trusted clients depending

*                on the certificate that was in focus in Authority

*                certificates view when Trust Settings view was entered.

*                Shows and changes correct Yes/No text for the Trusted client.
