allow drawdistance to change between 32 and MaxDrawDistance, configurable

 value default to 256, so should have no effect. Next steps needed: reduce
 client udp Throttles with distance, update childreen connections with
 significat movement and view range changes, Make disconnect be delayed in time, make disconnects be receiving region action not sender on region changes. Allow distance less than 256 to only connect to visible regions, even none. Make this be relative to camera and not agent position or region centers as it is now.
