Second go on balancing the ships.

Ship stats are all over the place right now, so I went through and adjusted them be on a more common ground as a basis for further adjustment. And to have something to adjust new ships in the future. (And I'll restart the thread about it on the dev forums.)
I've nerfed thrusts quite a bit. The Wave has 19G empty now instead of 30G for example.
Most lower thrust ships need about 10 minutes to reach LEO on autopilot.

It might need adjustments, like prices could be too high, deltaV-s too low, but they are proportional to each other, so we can adjust them more easily.
I've calculated prices by mass and full deltaV, and adjusted it for some crafts.

There seems to be a gap between low and high capacity crafts right now, so I think I'll plan for some medium crafts too. :)

Not much useful, but here's a graph with some of the data:
