Small Update: Bone shiver gain reduce + fixes

Hi everyone,

Public branch has been updated and here's what's new:

• Lower Bone shiver gain: Now the bone shiver effect gains 2x times slower.
  
• Bonefires upgrade: Now after igniting the bonefire - it will clear the nearest tiles of bone shiver, which should improve your experience walking around "forest" floors.
  
• Fatty, please be kind to me: Previously, if fatties were affected by bone shiver or other effects - they'd channel their effects to you when you're sqeezing through at an abnormal speed. This was fixed.
  
• New Memento select window: Now it should be more clear and intuitive.
  
• A variety of other fixes and balance changes: Some UI bugs shouldn't worry you anymore, as well as other stuff, like a Golden Mimic that was always following you, making the game a tid bit harder.
