Make doors more difficult to hack

[Carbadox]

Personally I'd make it so that doors to important locations like Security and the Bridge would have their own set of wires, seperate from the ones that all the other doors have. Also maybe make the maintance panel on the doors a bit more protected? So that when you screwdriver the door, you've got to wait for the actionbar to fill up, so that important doors arent as easy to get into.
