- The function getAuthUID() present in the helper fhcauth_helper.php
now tries to work always with CI session to get the uid
- REST_controller doesn't need anymore to handle the uid
- FHC_Controller and FHC_Model load fhcauth_helper in their constructor,
so any class that extends them now could call the function getAuthUID()
anywhere in the code
- The controllers don't need anymore to pass the uid to the models or to the
libraries
- Library FHC_DB_ACL load fhcauth_helper in its constructor and uses getAuthID()
