-tg- disease1

Wee! Readds Disease1, kills off disease2, and finally removes poop.dmi
(fucking piece of shit)

Needs WAY more testing, most of which I don't know how to do yet, because
I've never used this system. Fun!

Changes:
 - Virus2 has been removed completely.
  - Some symptoms have not been readded. Aka, none of them have been
    readded, I just wanted to get this shit ported.
  - Virology has been updated slightly to mirror -tg-'s boxstation, as the
    virus2 machines are gone.
 - Welcome back, disease1
  - The centrifuge, vials, splicer, analyzer, growerthing, have all been
    replaced by the PanD.E.M.I.C. 2220
  - No symptoms have been completely removed; However, vision symptoms
    have been disabled pending byond 510, and genetics symptoms have been
    disabled until "when I figure out how to fix them".
  - Advanced Mutation Toxin now uses a disease, which turns people from
    species, to slime person, to slime. Slime people are instantly turned
    to a slime.
  - Diseased touch now give people appendicitis. Yes, they VANT YOUR...
    appendix.
  - Virology now has a fridge with the following in it:
    - Antiviral Syringes
    - 1 Rhinovirus culture
    - 1 Flu culture
    - 1 Bottle of Mutagen
    - 1 Bottle of Plasma
    - 1 Bottle of Synaptizine
  - A few more things, which I can't remember and can't look at while writing
    this commit. Sometimes, git hurts.

TODO:
 - Test more shit and figure out how the PanD.E.M.I.C. works/is supposed to
   work.
 - Fix genetics symptoms.
 - Give vampires a less shitty diseased touch.
 - Add appendicitis event.
