It would give an option to fit drones to ships that hasn’t by default.
Maybe it could get some restriction on what kind of ships it could be fitted to,
like if the ship already has drone cap, the rig could not add up to the maximum the rig
itself allows. A Drone ship would get no benefits from them.
Example would be 2 light scout drones for T2 rigs, or 1 drone for T1 rig, so fitting two T2 and one T1
would give five scouts.
