Aghosted mobs no longer act as SSD

Removed player_logged var since it didn't serve it's intended purpose and replaced with aghosted var. Changed SSD checks to only look at client since regardless of what key gets set to I think we probably don't want players being told a mob is SSD if there is some client controlling it.
