v1.0.0 - Liquid propane for engine mods

Changes

• First release. A data-only mod with no parts and no code.
• Adds liquid propane (ExtProp_C3H8), the reaction liquid oxygen plus propane (ExtProp_Propalox, default mixture ratio 2.7) and a yellow and orange exhaust plume (ExtProp_PropaloxPlume).
• On its own it changes nothing in the game. Other mods use it for their engines, for example Prisma by Purrline Rocketworks.
