0.4.1

Really quick update for things I noticed were missing/not working

• Hitting two springs at the same time no longer plays the sound twice
  
• Fixed "show best times" button not changing if your best times are shown
• Removed sound/screen shake toggle buttons, replaced by the sliders
• If you are showing your best times and don't have a best time set, it will display a dash instead of just a blank space
  
• If you have timer enabled and no best game time, it will display a dash next to the world time instead of a blank space
