Add an inactive state on Switches and Sliders for accurate validation

When using switches and sliders in my form, they cause problems. If they are required and the user doesn't touch them, the wrong answer will likely be stored. If they are not required, and the user doesn't touch them, then the wrong answer will definitely be stored.

Create a switch with 3 positions/settings instead of 2. It starts in the middle of the oval which indicates no response has been recorded. Left side is off. Right side is on. Sliders would work similarly by needing an "off" position.
