Do an initial pass on balancing part and resource costs.

This includes fixing the masses of the augers: they were about a quarter of
the mass they should be.

Resources are set to something that seems reasonable based on real-world
numbers but using my own markup system.

The price costs are based on their mass with arbitrary (but consistent for
part type) markup: mass * RocketParts cost * markup scale. 1.2 for tanks,
12.8 for detectors, 1.5 for augers, 2.5 for recycling bins and pads, 25 for
the workshop, 20 for smelters.
Finish part deprecation for this time round.

I had forgotten to deprecate the old tanks and to remove the deprecated
parts from the science tree.
