Decay: Every Minute a Random Block Gets Deleted

📋 Changelog: v1.6

Atmosphere update: decay now looks and sounds like it hurts

• Added a decay sound effect that plays when a block type is about to crumble away
• Added a separate animal decay sound that plays when a mob type is wiped out
• The screen now shakes side to side while the sound plays, fading in and out smoothly
• Sound and shake start 1 second before the chat message, so you get a warning that something is about to vanish
• Block decay now shows a second chat message with the total number of blocks removed once the cleanup is finished
• Mob decay now waits for its sound before the mobs disappear, instead of removing them instantly
