purpose: Change of ownership
/chowner <itemID> <ownerID|ownerName>
Changes the owner of an object in space. The current owner and the new owner both have to be either EVE System or one of the NPC corporations. Also it only works on the entities you can spawn. It will not work at this time on the /entity deploy entities.
Change the owner of object with ID 100002800 to the Amarr Navy:
e.g. /chowner 100002800 "Amarr Navy"
The owner of an object may influence its behaviour if its behaviour has been customised with /behave.
