Positional locking/All-surface dockers

[Space Shaman]

Make it count as a regular ship, however turrets wouldn't regularly fire on it. You would need to select target it.

Third: Counters. This parasite-ship must have a way of being detected by the ship it is attached to (scanners?). It must still appear on the targeting sensors of other ships and be a valid target, attract heat-seekers etc.

My Idea for this is to require dedicated anti boarding ships. Perhaps the "magnetic grapplers" would have signatures, like docking points, that a turret could be configured to target.
