Sterling 0.4.0

Additions

• Added low temperature wrapper radiators.
• Added taller Stackable LFR.

Changes

• Changed System Heat engine configs to require System Heat but not its Fission Engines extra (mostly).
• Changed MSRs and PBRs to contribute to System Heat loops.
• Changed SULEU engines to have built-in Pebble Bed reactors.
• Moved thermal reactors out of Electric category and into Thermal category.
• Moved World Power out of Electric category and into distinct download.
• Moved all localization files into Agency folder.
• Updated Sterling Tankage: Added stack nodes that don't trigger the trusses.
• Updated radiators tech tree positions (stock and CTT).
• Updated radiators overall based on an RO dev's advice:
  • Their temperature curves are no longer linear but parabolic, following the 4th power of the given temperature.
  • High temperature radiators are passive and consume 0 ElectricCharge.
  • High temperature radiators do not sub-cool parts but low temperature radiators do.

Fixes

• Fixed Super heavy shield tooltip saying "Ablator? enabled" when it's not, in ThP variant.
• Fixed Icarus ICF engine's ISRU not asking for Deuterium under System Heat.
• Fixed a tank having the wrong title and description.
• Fixed excessive System Heat production in SULEU and thermal nozzles.
• Fixed node and ground collider offset problems in World Power parts.
• Fixed weak joint strength on LFRs.
