* Modified the disposals room to have a crusher and a stacking machine. It will allow the crew to recycle trash items.
 * Made conveyor belts invertable, to allow you to use corner pieces that are only intended for going backwards or forwards.
 * Added a new variable for disposal outlets which let you change their throw range. Default is 2 now.
 * The crusher can now be used by a screwdriver to de-emag it.
Viruses are less random and you can determine the level of symptom you would get. Virus food will generate low level symptoms, Mutagen will generate medium level symptoms and Liquid Plasma will generate high level symptoms.

Virologist starts with a small bottle of liquid plasma.
Filled in the gaps between the chem master with RGBA(255, 255, 255, 1) so you do not accidentally click on the floor anymore.
ChemMasters now has the green light overlay, which is only used by Pandemics but it looks better than red.
Updated changelog to a table of symptoms.
