panurgomatic 9793842a0e - Fixed vaccines not giving resistance if mob isn't infected.
- Added control interface for atmo mixer and pumps.
- Atmo meters now also show gas temperature
- Mecha logs.

/*
Every cycle, the pump uses the air in air_in to try and make air_out the perfect pressure.
node1, air1, network1 correspond to input
node2, air2, network2 correspond to output
Thus, the two variables affect pump operation are set in New():
air1.volume
This is the volume of gas available to the pump that may be transfered to the output
air2.volume
Higher quantities of this cause more air to be perfected later
but overall network volume is also increased as this increases...
