Added Fire Vortex to the 2nd layer
Added Tempest of Flame (rare massive green vortex found on the 7th layer)

Added Ghostbuster advancement for slaying the Tempest of Flame
Added Chomper (Large hostile fish) to the 5th Layer
Added Fourth Layer Mycelium and Mushroomy Deepstone
Overhauled the 4th layer with better large mushroom generation, different ground blocks and cookable puffball blocks
Added Territe geodes to the First Layer (not yet given a use outside the Eternal Descent pack)
Changed vortex type mobs to be marked as undead (since they are basically the grims from Lord of the Rings)
