Update 0.4.3

[h2]Changelog[/h2]
Fixes

• Refrigerator doors no longer open with LMB and no longer interfere with placing goods.
  
• The blue box of tea is now truly blue, not yellow.
  
• The cursor no longer disappears/appears when pressing Left Alt. This was an undocumented feature that caused problems if the player pressed Alt+Tab, so the cursor should no longer disappear. If you still need this function, it is now assigned to Right Alt.
  
• Visitors should now correctly approach refrigerators without doors, instead of getting stuck near them.
