[krbdev.mit.edu #5611] NIM Standard view selected color difficult to read

[Jeffrey Altman via RT]

Ticket 5676 implements a new identity header color schema.  

  Green   - active creds
  Yellow  - first expiration warning
  Orange  - second expiration warning
  Red     - Expired
  White   - No creds

Darker shades are used to indicate selection with Grey being the
selection color when there are no creds.

All text is displayed in black or dark grey depending on the selection
status.

The color schema is part of the UI schema (.csv).  This permits users or
organizations to define their own color schemes.  A UI control for
selecting color schemes can be added in a future release.
