+Property weights are: 
+"story_potential" -- essentially how many different ways the antag can be played.
+"trust" -- How much it makes the crew trust each other. Negative values means they're suspicious. Team antags are like this.
+"chaos" -- How chaotic it makes the round. Has some overlap with "valid" and somewhat contradicts "extended".
+"valid" -- How likely the non-antag-enemy crew are to get involved, e.g. nukies encouraging the warden to 
+           let everyone into the armory, wizard moving around and being a nuisance, nightmare busting lights.
+"extended" -- How much the antag is conducive to a long round. Nukies and cults are bad for this; Wizard is less bad; and so on.
+"conversion" -- Basically a bool. Conversion antags, well, convert. It's its own class for a good reason.
