[sldev] EnableSimulator not received

[Gareth Nelson]

Opensim actually sends EnableSimulator for all 8 possible neighbours
at startup. (I know this because I was the one to put multiple sim
support into it in the first place). LL's sims use a more
sophisticated setup which is dependent on your viewer frustum (i'll
spell it right one day!)
