Redone whisper code, now any /mob/living can be made to whisper by setting can_whisper (defaults to null)
and if needed overriding the whisper() proc to modify the mesage before calling the ..(message)
Like what was needed with /mob/living/carbon due to masks

Things can whisper from within an object/item and be heard by whoever carries them while they move. this did not work previously.

could modify the code later for things like XXX's muffled voice from the YYY ZZZ
