/* ===== DATETIME PICKER =====
   Свой поповер выбора даты/времени (backend/static/datetime-picker.js).
   Два класса, оба ставит сам модуль и только при pointer:fine:
     gt-dtp-on   — поповер работает;
     gt-dtp-icon — сверх того браузер умеет спрятать свою кнопку календаря,
                   значит рисуем свою. Firefox этого не умеет, там остаётся
                   его собственная кнопка — она и открывает наш поповер.
   Без классов (телефоны, страницы без скрипта) поле полностью нативное. */
