- Changed calling convention of delete_list_member() & delete_list_admin()
  - delete_list_*() may report error via "stash" when the email doesn't exist.

Add the new list parameters default_owner_options & default_editor_options to control default attributes of owner & moderators (#989)

sympa.pl: --add can take a --role option

Now Sympa::List::add_list_member and Sympa::List::add_list_admin use stash.

    malformed input by users/clients: "user" level should be used.
