[refactor] BaseNPC now uses Entity XYZ fields for handling positions

Browse Source 
- fixed many references to Entity.appearanceData.i[XYZ] to use the base Entity XYZ values
- BaseNPC::enterIntoViewOf grabs the position from the base Entity XYZ values
- NPCManager::updateNPCPosition updates the base Entity XYZ values
- MobAI.c/deadStep() also sends it's packet based on the Entity XYZ values
