-Got rid of a redundant del() in the PANDEMIC. Fixes Issue 1116.

-Added a new symptom. Voice Change will randomly change the voice of the affected mob. It isn't obtainable by Mutagen and I'll likely put it in the virus crate when I have more dangerous viruses.
-Added two new symptom procs. Start() will be called once and it'll be called when the advance disease processes. Allows you to setup stuff for your symptom. End() will be called before the disease is deleted.
-Diseases that spread by blood won't spread by contact anymore. You will need to directly inject someone to get them to catch the disease.
-Put a limit on shivering and fevers.
-Added a specialvoice variable. You can use SetSpecialVoice() to set a special voice that the player will say instead. To unset it, use UnsetSpecialVoice(). GetSpecialVoice() will return the player's special voice value.
-Added two DEFINEs for the limit which is how much a human can take before taking burn damage from heat or coldness. 
-Some symptom value changes.
