Project make pathology suck less [New path symptoms, tweaks, nerfs, and rebalances]

[Erev]

Not a bad patch. I am disappointed by the lower symptom nerf I get it. And not losing your work is well worth the cost. If there is one thing that I'd add it would be an incubator - insert a pathogen and you get a supply of that pathogen that you don't need to worry about culturing in beakers forever. If you want to do multiple strains? You gotta go old school (or buy an upgrade). But for general work? Use the incubator.

I am also hoping that some/most of the new symptoms are neutral or beneficial. Or that more are added. (Though eventually we'll need a way to find a symptom we want....)
