sympa.pl: Adding a new option --add, and expand --add and --del options

Included owners won't be removed even if they have been removed from the data source (#1272)

Build process: Use configured Perl on "make tidyall"

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

Now the list parameter member_include may have reception & visibility as owner_include & editor_include do (#989).

Parameters to specify defaults (profile, reception & visibility) in *_include parameters may be optional and values in corresponding default_*_options parameters will be used as the defaults.

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

Change calling convention of Sympa::List::delete_list_admin() to avoid misuse.
