Subject: From: Alan M Webb <alan_webb@us.ibm.com>

  Added support for access control lists.
  Scene: Added test to AddNewClient for an entry in the access
         list when connecting to a region with limited access.
  EstateSettings: Added an HasAccess(UUID) property to test for
         an entry in the estate's access list.
  RemoteAdmin: Add RPC calls for admin_acl_list, clear, add,
         and remove.
