function cas_user in CAS 6.3

Implementation of hook_user().

Delete: When a CAS user is deleted, we need to clean up the entry in {cas_user}. Insert: When a user is created, record their CAS username if provided. Load: Adds an associative array 'cas_names' to each user. The array keys are unique authentication mapping ids, with CAS usernames as the values. Update: When a user is updated, change their CAS username if provided.
