v1.5.5 - small tweaks

Novelties:

• We now have Rich Presence!
  
  You can now tell whether your friend is sitting in a multiplayer lobby, trying their best with Arcade, or just stuck on Canyon.
  

Tweaks:

• "Coyote time" is now ~100ms (6f) instead of ~66ms (4f)
  I don't think most people will be able to tell the difference.
  
• Pressing Jump a couple frames early when swimming is now allowed.
  This also means that button-mashing the Jump button in panic will work slightly better.
  
• It is now a little easier to jump out of the water.
  

Fixes:

• Fixed an error when quitting in the middle of a Bomb Pong match.
