[krbdev.mit.edu #5782] NIM: APP: BUG: Initial cursor position does not track selected identity

[Jeffrey Altman via RT]

When NIM starts it loads the identities into the list control.  The
first identity that is added automatically receives the cursor focus.  
NIM then computes (in the background) credential state for each
identity.  The list is re-ordered so that identities with credentials
are listed first.  The first identity in the list is then "selected".

If the "selected" identity was not the first identity added to the list
control, the cursor and the selection will be inconsistent.  

This results in confusing behavior for end users when the "Obtain New
Credentials" toolbar button or menu command is executed.
