Maxwell's puzzling demon v1.1.4

[h3]Levels update[/h3]

• Fixed 8-5 to prevent an unintended solution.
  
• Changed the layout around 0-λ and 0-μ in w8 so that reaching them requires two players.
  
• Adjusted some levels. (This does not affect solution of each puzzle.)
  

[h3]Other changes[/h3]

• The display of piston order, which is unlocked by reaching 8-2, can now be toggled with the tab key.
