/*
Check object's ownership and friends (plot and door)
Original concept by RimBlock (github.com/RimBlock)
Extended by Bruce-LXXVI to support different target objects
and allow fine grained access policies
Parameters:
_this select 0: object - player calling this function
_this select 1: object - target to check ownership and friendlies of
Returns:
_return select 0: bool - player is owner of target object
_return select 1: bool - player is friends with owner of target object
_return select 2: bool - player is plot owner
_return select 3: bool - player is plot friend
_return select 4: bool - player is plot management admin
_return select 5: bool - player is target friend
_return select 6: bool - player is target management admin
_return select 7: string - detected target type
2,3,4: always false if no plot nearby
5,6: always false if _target is not a supported target
