Release 7866d1f

Implement day-night cycle and player spawn handling

- Introduced a new dayNight.gd script to manage the day-night cycle, including a signal for time updates and initialization of time variables.
- Updated main.gd to connect the new time_tick signal to relevant UI updates and player spawn handling.
- Refactored Multihelper.gd to modify the player_spawned signal, now including player information for better handling of player-related logic.

These changes collectively enhance the game's time management and player interaction features.
