v1.0.1

• Fixed bug where creatures could block newer creatures from spawning in dens.
  
• Tweaked spawn list. Specifically, fixed wave 1 spawning two pink lizards, wave 10 now spawns substitute creatures when the room has no sky exits, and made centipede spawns choose IDs from a list mostly contained of long centipedes.
  
• Added proper mod support with respect to creature types in the wave spawn data.
  
• Added ability to specify IDs for creatures in the wave spawn data.
