[PR] Pathology Rework: Modernizing to TGUI

[colossusqw]

We haven't had pathology in a long while cause the customsation made pathogens spread too fast and had people having to quarantine themselves constantly.
I wish I would say: "Antags were too good."
But no... it was also people being funny, making funny diseases spread while not being antag.
So they shut it off and remains shut off...
If anything pathology can return but ONLY with more limiting factors on it so epidemics won't become common when they are back.
Aka all viruses in pathology will be a weakened variant that can't spread unless "Traitor items" are used.

I was not there for the new pathos testing, but from what i heard it was relatively more balanced than the original. I've also heard stuff about how the main issue with it may have been the fact it was a 1 week new thing that kind of made everyone want to mess with it, and not as much the system itself not being good. So I'm not sure if going even farther than we "have" now without doing more testing is that good of an idea yet....
