Code: Exp from pet kills and a pointer check

[IASoveraign]

Small changes to attack.cpp.

NPC::Attack
Added a pointer check that keeps the zone from crashing in one instance.

NPC:eath
Adjusted the death code exp to be like eqlive (i.e. gives exp if PC pet gets last hit and you are "killer" but not if last hit was NPC or NPC pet).
