SilverIce 012be82c86 [11818] update creature's unit part(update spell events, auras, movement) while in death. thanks to rsa for making tests 
this allows us update creature's death persistent auras, fall died creatures in natural, non hacky way

also fix the bug that creature starts waypoint movement not from begining at respawning. thanks to Grz3s for reporting
