* [updated] Mantis Bug #4204 Adjust aggro chance to take skill into effect. High skill vs CL less likely to aggro. always a 5% chance to aggro on a success, unless the creature can provide no more samples in which case it dies. Also added some extra adjustments to ensure if you sample a creature to death you may NOT harvest from the corpse. Also Fixed a missing mean * level in the dna manager. for some reason have a line got cut off, recommiting
