    EPlugin: update the ACL add sub-dialog before displaying
    
    * update the "add" variant of the ACL add/edit dialog with
      data previously read from the server
    * we fill the combo box with the access_id entries we have
      for the folder, but do not set a default
    * the combo box entry field is thus empty to clarify that
      we're adding a new entry, but the already-existing
      access_ids appear when the dropbox is opened so we can
      pick one and change it (should ease editing in some
      cases)
    * once we can query address books or directory services
      via the "Retrieve" button, more access_ids could be
      added to the combo box for easy selection
