Experimental tweak, I'll revert this if everyone hates it but for now I want to see how things will be if airlocks use the environmental power channel.

-Changed airlocks to use the environmental power channel.
-Changed all airlock controlling devices to use the environmental power channel.
-Changed shutters to use the environmental power channel.
-Changed pipe meters to use the environmental power channel.
