New Torch/flashlight Drone

Added a torch/flashlight drone for visual effect. The GM can choose that the player can only explore a certain area with that drone, or hidden objects will be revealed if that specific drone enters a region. (easiest way is using WHEN Region Enter IF Match string Triggering actor's display name matches pattern 'Torch Drone').
The flashlight is greenish to suggest that the light can be infrared (invisible) light or light amplification, so it may be not a literal light but something more stealthy
