Add GetWorldMarker, return position from WorldMarker, rename CanSetWorldMarker

Browse Source 
- WorldMarker() now returns x,y,z,areaId on success (was just 1)
- New global GetWorldMarker(index) for querying marker positions
- Rename CanSetWorldMarkers → CanSetWorldMarker (singular)
- Addon uses WorldMarker return values directly instead of GetMarkerDef
