Starter zone needs rework

[icydee]

Total redo of the starter zone (yet again) ideally we will have a starter 'sector' and all stars in that sector will be good starters. Currently the starter zone code is disabled and any star is accepted.

I think part of the discussion was to have any stars within x units of a KME outpost be considered (relatively) safe, though exactly how we'd do that, I'm not sure yet. This would allow for starters all across the expanse. The NZ may simply go away.
