multiple fixes to common damage and death

Damn 5 minute edit timer....

anyways, since my explanation was rather bad, the death struct changes fix the "you crush mobname for # damage" no matter how you killed it messages, that was even displaying from spells.

now no damage message is displayed by client when mob dies, so calling death routine will kill a mob with only the X was slain by X message, so no more "mobname tries to punch itself but misses" on #kill for example either.
