make running ghost placement of power poles work better

[Mendel]

If I run and use ghost placement of power poles, the ghosts are placed right next to each other.

Better would be for them to be placed like they are when doing manual running placement. (max distance between poles or placement such that everything near poles would get power while maintaining as long distances as possible)

This mainly came up to me as an inconvenience when I was going for the "You are doing it right" achievement as fast as possible so I was ghost placing *everything* before making blueprints.
