Add way to allow Drones to hide behind a wall

[MaartenKok8]

Two options:

1. A frame (similar to a logistics one) that can be put on any block, and a Drone will treat as it were air in the pathfinder. The player will have to build something themselves (like a piston door) to remove the block when the drone wants to travel through.
2. A specific Drone Hatch that allows drones to go through and opens automatically, and can be camouflaged.

I prefer the first, because it's more generic and is a harder option, requiring people to come up with their own doors. I have to see if it's easy to work with, as frames usually have a block they're 'framing', and if the piston door removes it, it needs to stay.

If you do end up adding the first option, I'd recommend having a way to detect if a drone wants to pass through, like having a linked frame to send a redstone signal to or having the frame send a redstone signal. (Or don't, you did add Universal Sensors, after all)

Or at least a "drone present in area" condition for Universal Sensors, to be coupled with a GPS unit in order to detect when a drone is near the door.

Kinda already present actually: Entity Tracker -> Within Range -> Filter: "@drone"
