A few new mechanics components.

[Kubius]

I'm glad these components have been added into the game. The hand scanner in particular is really boss for secure "doors" made with graviton accelerators and pressure plates. Getting the pressure plates to toggle was awful, though.

I figured out a solution - button > toggle component with settings of 0 and 1 > selection component and pressure plate > selection component > signal check component > accelerator. Really convoluted but it works great.
