Redo Saxitoxin's behavior, keep tweaked current version as generic space pesticide

[colossusqw]

Oh, I dont mean to nerf the syndicate version, rather alter it to a saxitoxin with new behavior that works more like actual saxitoxin. Neurotoxic paralitic saxitoxin would be excellent for combat just like current organophosphate saxitoxin, fast acting and debilitating enough. I dont really want the syndicate to get the pesticide version.
