SpaceDust support for GEP

[LouisB3]

Resources are placed using the following as references:

• GEP's resource definitions
• GEP's atmospheric compositions in the CelestialBodies pdf
• Rational Resources' assigned templates
• SpaceDust's configurations for stock

• Seven SpaceDust "core" resources
  • [x] Oxidizer [oxygen]
  • [x] Xenon (Gas)
  • [x] (Lqd) Hydrogen
  • [x] Argon (Gas)
  • [x] Antimatter
  • [x] (Lqd) Deuterium
  • [x] (Lqd) He3
  • [x] Not LiquidFuel
• Six DustBunnies CRP resources
  • [x] (Lqd) Ammonia
  • [x] (Lqd) CO2
  • [x] (Lqd) Methane
  • [x] (Lqd) Nitrogen
  • [x] Rock
  • [x] Water
• Support for optional mods:
  • GEP_Rescale:
  • [x] rescale atmo resources to new atmo heights
  • [x] rescale exo resources to new parameters (typically x2.5)
  • GEP_Primary:
  • [x] delete stock system definitions (especially for Kerbin/Sun)
  • [x] rename Nodens/Grannus definitions as Kerbin/Sun internally
  • [x] change Nodens definitions to alwaysDiscovered/alwaysIdentified where relevant

Ignore the following resources in RR's ExoRock template, which is shared by nine GEP bodies; otherwise they would be ubiquitous:

• Oxidizer
• LqdHe3 (especially this one, as this is supposed to be a highly challenging/rewarding ISRU experience in FFT)
• LqdCO2
• Rock (maybe add this one back, as it's the primary source of Rock in GEP via SpaceDust)
• Water

[LouisB3]

Misc resource placement notes:

• Ignore atmospheric resources for Grannus itself. GEP has these but they're not relevant to normal gameplay.
• Ignore the exospheric resources for Grannus added by RR (keep the ones added by GEP itself). There are so many of these that one could basically fill up on everything by parking in solar orbit.
• Ignore the LqdHe3 around Nodens added by RR, as this is supposed to be a highly challenging/rewarding ISRU experience in FFT
• Place Antimatter around Nodens and Sirona, as these are the active magnetospheres (according to the KH patch). Possibly Grannus as well.
• Place Rock/Water around Sirona's rings; see DustBunnies patch for JNSQ's Lindor
• Ignore Toutatis' atmospheric oxidizer added by RR (this is a Duna-like atmo)
• Ignore Nodens' exospheric oxidizer added by RR (doesn't match Kerbin)
• GEP places ArgonGas at Sirona (which has none in its atmosphere, per CelestialBodies.pdf) but none at Toutatis (which does). Place ArgonGas at Toutatis based on its atmosperic composition and very small amount at Sirona (0.1% by atmo composition).

Unimplemented resource placements:

• Exospheric Antimatter at Grannus

Remaining questions:

• [ ] LqdHydrogen placement at Sirona is derived from the SpaceDust config for stock Jool, which may be incorrect (see SpaceDust issue)
• [ ] SpaceDust documentation mentions that bands can be configured to vary by "air density" but says that the density curve is specified in atm (a unit of pressure). Does this compensate for temperature automatically, or should that be incorporated into specified abundance values? Pressure vs density distinction affects final abundance values if based on atmospheric composition for a given body, due to differing temperatures
