Having an infection raises your body temperature

Also the toxin damage taken during INFECTION_LEVEL_ONE is greatly
reduced.
Fixes robotic internal organs getting infections.
Fixes the organ_failure random event. Forgot to set the affected organ
as needing processing.
IPCs actually take heat damage from temperature now

Also fixes the healthanalyzer still not scanning IPCs properly (scanning
them when it shouldn't)
