Add CSS flag dropdown select with lipis flag-icons

- css/flag-icons.css: lipis 4x3 set, 1x1 stripped, paths → ../icons/flags/
- countries_inc.php: asort, Smarty assigns, loadCss (PKG_PATH not PKG_URL);
  PHP files reduce to single require()
- flag_select_inc.tpl: custom dropdown with .fi CSS flags, search filter,
  jQuery open/close; fsName/fsValue/fsId/fsSize; min-width 300px;
  line-height:1.5em on flag spans
- html_head_inc.tpl placeholder; display templates keep {biticon istyle=flag}
