isFCS -- Checks if a member is fleet command staff.
($pin, $hconly = "no", $current = "Yes")
This function checks if member with id $pin is a member of fleet command staff, regardless of which fleet with certain applicable conditions.
$hconly, if set to "yes", includes only CO's and XO's in the check. If left specified as "no", SO's are included in the check. Setting $hconly to something else assumes "yes".
$current, if set to "Yes", only checks active fleets. If set to anything else, all current and inactive fleets are checked.
This function returns true if the member is in the command staff of a fleet that meets the specified criteria. It returns false otherwise. This function returns false on failure.
