Explore possibility of a native slider interaction for Wrench

[terracoda]

Because the Wrench only moves up and down, it might be a good fit for a native slider interaction when the sim gets looked at in the future.

While there may be reasons not to use a slider; here are a view benefits:

• works natively with the all arrow keys, no need to use Alternate WASD keys
• a slider interaction natively prompts use of the Arrow keys and is easily understood by screen reader users
• there may be benefits of using aria-valuetext for object responses (and there may not be)
• can use aria-orientation="vertical" to natively cue the orientation of the Wrench's movement

Other sim examples:

• John Travoltage uses sliders for the Foot and Hand ("Leg Swing" and "Arm Swing"), and sliders worked very well those interactions eventhough the Leg and Arm do not look like sliders.
