MetacatUI

Currently, the Publish button is visible and enabled if a user is logged in and has permission to publish a new identifier. Once a DOI has been assigned, however, the Publish button should be disabled as there is no need to assign a new DOI to an object that already has one. Also, the Publish button should be disabled for any obsoleted versions of an object, as they can not be updated() and therefore assigning a DOI doesn't make sense. Only when a user has created a new, non-doi version of an object should the button be enabled again.
