I've run into a problem with this patch.  For observers, p_status is not
being sent correctly.  Before patch, they always get status sent as
PALIVE.  With patch, status changes to PEXPLODE upon locking onto a
ship who is in combat, and it never changes back.  I noticed this
when trying to look at observer tractors..they weren't displaying, and it
was because observer thought he was dead (p_status == PEXPLODE) so they
weren't drawing.
