Demo Patch 0.6.5

Hi everyone!

I just updated the demo with some content and fixes. Here are the patch notes:

• NEW employee level/promotion system.
  
• Addressed an issue for some users where all game objects were yellow, except for the sky. Please let me know if you still experience this as I am not able to reproduce this issue myself.
• Reworked the umbrella and cover system. They are now separate objects that you can place on tables.
  
• Added a Gazebo object to demonstrate what can be done with the reworked system.
  
• Added multiple new gameplay music.
  
• Fixed the bug where loading a save file would put the camera on the ground initially.
  
• Fixed a bug where stalls couldn't sell food because it was missing an ingredient that it didn't even need.
  
• Increased max camera zoom distance.
  
• Added more preset colors for customization.
  

Thanks again for playing! Stay tuned for the full release coming soon.
