Parasitus Fixes

7dtm no longer spawn in torches again

-Adjusted damage done by metal spikes, wooden spikes, knives and razor wire

-Adjusted bleeding to be more fair, you should no longer die so quick so easily when wearing OP armor due to just bleeding when being swarmed.

-With hostile world invasion mod, Anti-Skybase mechanic has been added. If you go too high, you will be warned only 3 times that parasites can be more dangerous when living in the sky. If you decide to live in the sky anyways (being top of a mountain isn't an issue) then every parasite hoard will be dangerous flying parasites designed to bombard your home. Being so high in the sky to the point mobs are unable to load causes progress to slow as world progress is tied to mobs being killed by parasites, so this mechanic should hopefully prevent players living so high up in the sky and ruining the pacing.

-Bandits, survivors and 7dtm soldiers no longer despawn inside their bandit structures.

-Dynamic tree leaves now change with overlast

-Added a intro upon world creation
