Better Circuits v2 for People Playground

Rework of 'Better Circuits', adds new circuits with new behaviour

Better Detector:
A 0-delay, signal-efficient, object detector. Green toggles detector, red toggles detection specifier, blue toggles detection mode

Better Key Trigger:
A 0-delay, single-signal key trigger
