New tool for Engineering Borgs

[Sundance]

You could also make it so that using a crowbar turns the valves saving the need for adding a new item.

Only if you take the crowbar away from other Borgs. The point is to make the engineering Borg relevant by giving it, and only it, the power to run the engine, as it was back when we had the singularity.

If you do that, there'd be even less reason to pick anything other than construction

Taking crowbar away from borgs is rather pointless, and the crowbar is needed for alot of things.
Giving them the Valve key lets them be the borgs only to run the engine.
I really think this needs to be added pretty quick, it's a bit of a faux pas that an engineering borg cannot run the engine.
Here, I sprited the valve key, took me all of 20 minutes.
