Patch with fixes

Corrected:

• The waiter has been moved to the center of the hall.
• The tutorial has been reworked. It now saves progress and can't be skipped or broken (I hope).
• Fixed a bug that saved the volume setting, but still reset to the maximum value when rebooting.
• Now the customer counter counts them correctly.
• Now the amount of GodPower from customers depends on the Cafe level.
