Reverted the gravshaft controller to function more like previous version and added a node for platform state (second input node in from left on top.)

On 'Up' left input change to high, will set above shafts/units to Off, below to Up, and activate a platform on that Unit.
On 'Down' input change to high, will set above/below shafts/units to Down, and activate a platform on that Unit.

By then wiring each Unit to respective floor buttons, you can utilize them properly as a grav elevator shaft.

(Definable buttons shown from my Macrochip mod here also.)

Feedback on the Gravshafts just added will be appreciated!

Added Gravshaft and Gravshaft Control objects, an alternate elevator system to the gravpads and gravrings. These function much like graviton rails but vertically.

Both Gravrail and Gravshaft Controls will send signals along adjacent rails/shafts up to and including changing the next control unit met, although the next control units won't send the signal further.

Left input will change direction to left when its connection changes to high.
Middle input turns the control unit on and off. If connected, the control unit cannot be interacted with to cycle.
Right input will change direction to right when its connection changes to high.

Left output is high when current direction is to the left.
Middle output is high when current direction is left or right.
Right output is high when current direction is to the right.

Upper left input will change direction to up when its connection changes to high.
Lower left input will change direction to down when its connection changes to high.
Middle input turns the control unit on and off. If connected, the control unit cannot be interacted with to cycle.

Middle output is high when current direction is up or down.
Upper Right output is high when current direction is up.
Lower Right output is high when current direction is down.

Added graviton rails.
