Стартовый хаб с порталами, песочница отдельным пакетом, присед

- World/Hub: маленькая стартовая комната (код, без ассетов) с порталами на карты;
  новые карты добавляются записью в PORTALS (влезает 6 порталов).
- Песочница (main.tscn) вынесена в world.pck и качается при входе в портал;
  основной пакет игры вместо 19.7 МБ стал 2.1 МБ. Выходы из карт ведут в хаб.
- Экспорт: три пресета (Web — движок и хаб, World, Backrooms).
- Присед: удерживать C (на бегу Shift+C по-прежнему подкат), скорость 3.5.
