 Add a "Set default" sub menu to the Network Identity Manager
 notification icon context menu.  The submenu will display a list of
 identities that the user can select as the default identity.

 Each identity that is displayed in the sub menu will be colored the
 same way it is colored in the basic view to provide a hint as to the
 state of the credentials belonging to the identity.
