Hotfix for demo patch 0.6.0b

Hi everyone,

Just some quick fixes and adjustments for the latest demo update.

• Added additional keyboard controls for the camera (specifically for those using touchpads and ergonomic mouse).
  
• Changed object rotation keys to Z and X. Camera rotation is now using Q and E keys.
  
• Opening the Ingredients Market now pauses the game so you don't miss the new time limit.
  
• Added notification for when market is open.
  
• Fixed a bug with the customization wheel buttons sometimes not responding correctly.
  
• Some minor text corrections.
  

I hope you're enjoying the demo!
