Proposal: relative resource concentrations for atmospheric resources

[ChrisAdderley]

The very small concentrations of many resources in atmospheric, oceanic and exoatmospheric resource definitions are entirely impossible to harvest given that the KSP ResourceMap cannot sample values below 0.001.

This PR proposes shifting atmo, exo and oceanic distributions to relative concentrations, where 100% is now the maximum harvestable resource concentration anywhere. This has some advantages:

• Tiny resource concentrations are now harvestable
• Every resource can now take advantage of the full range of values (0.001 to 100) to provide maximum granularity
• Easy player communication of the "best" places to harvest resources
• Modders can easily adjust the rate at which resources are harvested purely with the Efficiency field of a converter.

In addition this PR adds support for LqdDeuterium and Antimatter as resources, and modifies the distribution of LqdHydrogen somewhat.

The problem with this proposal is that it is impossible to define a maximum density. Instead, I propose using CRP as a non linear scale below 1. I have posted the details a long time ago on the CRP discussion forum. The big advantage is that allows you to define planets atmosphere ranging from 100% to 0.000001%. Notice I have already callibrated rare resourses for helium3 lqdDeuterium and lqdHydrogen using this non linear scale.

It's probably better to actually discuss this on the forums so that other stakeholders can participate.

@ChrisAdderley - saw this was still being tweaked as of an hour ago - let me know when this is clear to merge in. Thanks!

[ChrisAdderley]

@BobPalmer I addressed the comments by @sswelm just now. I believe it is good to merge, I will leave the tweaking of the version (I suggest bumping the major) to you.
