AliasdomainHandler.php:

- set $domain_field to enable permission handling (and to get a list of
  allowed/available domains)
- fill $this->struct['alias_domain']['options'] and 
  $this->struct['target_domain']['options'] with available domains that
  are not yet used as alias domain
- override init() to get "All domains are already aliased" error message
  out as early as possible (and let init() fail in this case)
