Medical ai command

If player is leader of group and not uncunscious, AI has to be ordered to move close to patient.
If there is a nearby unit able to help, he will do so.
If patient is an enemy, he needs to be uncunscios to receive help. He will lose his weapons and get a captive/surrender state.
This may find non-local units. This entire script is meant to work for group member AIs only, which are always local to the same PC. This will fail in MP eventually.
