NanoUI Gas Cooling/Heating System
* Created Nano UIs for the Gas Cooling System and Gas Heating System
* Standardized the reference structure for procs (they now use use full paths, instead of relative)
* Standardized the names of each machine ("gas cooling system" and "had heating system") for both the object and the UI title
Added no-network check to heat_source to fix a runtime if not connected to a network.
NanoUI Gas Cooling/Heating Update
* Fixel incorrect text label in the gas cooling/heating system NanoUI.
