Selective Spider Removal
Removes all Skin and Blood Spiders (Biological Spider Types) from the game, no other effects. DOES NOT EFFECT ROBOT SPIDERS (for that see my other mod: Absolutely No Spiders)
Version 2 also Adds Special "Bonedog Spider Replacements" to all deleted spider spawning squads (so challenge is maintained), note that these squads are not like ordinary bonedogs, approach with caution.
