Virology - NanoUI, gameplay tweaks, bugfixes

Forum Thread:
http://baystation12.net/forums/viewtopic.php?f=18&t=9941

Summary:
- Feature: Enhances the virology systems with responsive NanoUI interfaces.
- Feature: Also adds NanoUI to Smartfridges since there is one in Virology.
- Feature: The centrifuge and isolator were almost identical. I tried to differentiate them by making the Isolator more of a "Disease Detective" computer. Identify "patient zero", look-up recognized diseases in the database, print out reports showing people just how screwed they are... Its also faster at isolating pathogens. The centrifuge is now faster at isolating antibodies.
- Feature: You can splice a virus' Affected Species.
- Enhancement: You can add any kind of toxin to the incubator to raise its Toxicity. This reduces the infection rate of viruses, but too much will kill the virus entirely. Toxins in blood also help speed up isolating antibodies.
- Minor Enhancement: Corrections of minor spelling mistakes.
- Minor Enhancement: The weakest symptom stage starts at 1 and goes up to 4 instead of starting at 4 and going down. This brings the text in-game in line with how people talk about symptoms.
- Bugfix: Not being able to "vend" items from a Smartfridge if the item has the "\improper" macro in its name.
- Bugfix: If you had multiple samples from the same donor lying around the lab, breeding a virus into one sample would infect all of the others.
- Dev: Adds data/ folder to .gitignore because I'm tired of accidentally committing those files.
- Lolz: you can kill a virus by putting it in the microwave.
