* Description:   Implementation of class CCertManUIViewAuthority

*                Updates Options list depending of the number of

*                marked and unmarked certificates in the listbox.

*                Handles softkey and Option list commands.

*                Handles certificate deletion including confirmation and

*                read-only notes.

*                Shows certificate details view with appropriate

*                warning notes if certificate is corrupted/expired/not valid.
