Make mechanized airlocks and automatic dispensers need power to use automation

[Kharmah]

What it says on the tin. I think they should need power for the automation to work. I always thought it was weird that the door could open and close without any power. It almost seems that the need for power to the item was planned but forgotten. I'm not sure what it would do to other player's automation but I feel that it would help rein in some of the shenanigans.

They do operate slower without power. I think I agree for the automatic dispenser, but not the door (this is shared with bunker doors), as that would break too many builds. Automatic dispensers for a time needed power to even dispense, but that was reverted because it made them next to useless again (they're ideal for "sweep and drop" management of debris, using power and making heat for that is ridiculous).
